Add 'about-filter' and 'repo.about-filter' options

These options can be used to execute a filter command on each about-page,
both top-level and for each repository (repo.about-filter can be used
to override the current about-filter).

 CGITRC(5)
 ========
 
 
 NAME
 ----
 cgitrc - runtime configuration for cgit
 
 
 SYNOPSIS
 --------
 Cgitrc contains all runtime settings for cgit, including the list of git
 repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
 lines, and lines starting with '#', are ignored.
 
 
 GLOBAL SETTINGS
 ---------------
+about-filter::
+        Specifies a command which will be invoked to format the content of
+        about pages (both top-level and for each repository). The command will
+        get the content of the about-file on its STDIN, and the STDOUT from the
+        command will be included verbatim on the about page. Default value:
+        none.
+
 agefile::
         Specifies a path, relative to each repository path, which can be used
         to specify the date and time of the youngest commit in the repository.
         The first line in the file is used as input to the "parse_date"
         function in libgit. Recommended timestamp-format is "yyyy-mm-dd
         hh:mm:ss". Default value: "info/web/last-modified".
 
 cache-root::
         Path used to store the cgit cache entries. Default value:
         "/var/cache/cgit".
 
 cache-dynamic-ttl::
         Number which specifies the time-to-live, in minutes, for the cached
         version of repository pages accessed without a fixed SHA1. Default
         value: "5".
 
 cache-repo-ttl::
         Number which specifies the time-to-live, in minutes, for the cached
         version of the repository summary page. Default value: "5".
 
 cache-root-ttl::
         Number which specifies the time-to-live, in minutes, for the cached
         version of the repository index page. Default value: "5".
 
 cache-size::
         The maximum number of entries in the cgit cache. Default value: "0"
         (i.e. caching is disabled).
 
 cache-static-ttl::
         Number which specifies the time-to-live, in minutes, for the cached
         version of repository pages accessed with a fixed SHA1. Default value:
         "5".
 
 clone-prefix::
         Space-separated list of common prefixes which, when combined with a
         repository url, generates valid clone urls for the repository. This
         setting is only used if `repo.clone-url` is unspecified. Default value:
         none.
 
 commit-filter::
         Specifies a command which will be invoked to format commit messages.
         The command will get the message on its STDIN, and the STDOUT from the
         command will be included verbatim as the commit message, i.e. this can
         be used to implement bugtracker integration. Default value: none.
 
 css::
         Url which specifies the css document to include in all cgit pages.
         Default value: "/cgit.css".
@@ -189,96 +196,99 @@ root-readme::
         The content of the file specified with this option will be included
         verbatim below the "about" link on the repository index page. Default
         value: none.
 
 root-title::
         Text printed as heading on the repository index page. Default value:
         "Git Repository Browser".
 
 snapshots::
         Text which specifies the default (and allowed) set of snapshot formats
         supported by cgit. The value is a space-separated list of zero or more
         of the following values:
                         "tar"   uncompressed tar-file
                         "tar.gz"gzip-compressed tar-file
                         "tar.bz2"bzip-compressed tar-file
                         "zip"   zip-file
         Default value: none.
 
 source-filter::
         Specifies a command which will be invoked to format plaintext blobs
         in the tree view. The command will get the blob content on its STDIN
         and the name of the blob as its only command line argument. The STDOUT
         from the command will be included verbatim as the blob contents, i.e.
         this can be used to implement e.g. syntax highlighting. Default value:
         none.
 
 summary-branches::
         Specifies the number of branches to display in the repository "summary"
         view. Default value: "10".
 
 summary-log::
         Specifies the number of log entries to display in the repository
         "summary" view. Default value: "10".
 
 summary-tags::
         Specifies the number of tags to display in the repository "summary"
         view. Default value: "10".
 
 virtual-root::
         Url which, if specified, will be used as root for all cgit links. It
         will also cause cgit to generate 'virtual urls', i.e. urls like
         '/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
         value: none.
         NOTE: cgit has recently learned how to use PATH_INFO to achieve the
         same kind of virtual urls, so this option will probably be deprecated.
 
 REPOSITORY SETTINGS
 -------------------
+repo.about-filter::
+        Override the default about-filter. Default value: <about-filter>.
+
 repo.clone-url::
         A list of space-separated urls which can be used to clone this repo.
         Default value: none.
 
 repo.commit-filter::
         Override the default commit-filter. Default value: <commit-filter>.
 
 repo.defbranch::
         The name of the default branch for this repository. If no such branch
         exists in the repository, the first branch name (when sorted) is used
         as default instead. Default value: "master".
 
 repo.desc::
         The value to show as repository description. Default value: none.
 
 repo.enable-log-filecount::
         A flag which can be used to disable the global setting
         `enable-log-filecount'. Default value: none.
 
 repo.enable-log-linecount::
         A flag which can be used to disable the global setting
         `enable-log-linecount'. Default value: none.
 
 repo.max-stats::
         Override the default maximum statistics period. Valid values are equal
         to the values specified for the global "max-stats" setting. Default
         value: none.
 
 repo.name::
         The value to show as repository name. Default value: <repo.url>.
 
 repo.owner::
         A value used to identify the owner of the repository. Default value:
         none.
 
 repo.path::
         An absolute path to the repository directory. For non-bare repositories
         this is the .git-directory. Default value: none.
 
 repo.readme::
         A path (relative to <repo.path>) which specifies a file to include
         verbatim as the "About" page for this repo. Default value: none.
 
 repo.snapshots::
         A mask of allowed snapshot-formats for this repo, restricted by the
         "snapshots" global setting. Default value: <snapshots>.
 
 repo.source-filter::
