Add commitdiff between commit and each of it's parent
A link is added next to each parent of a commit, leading to the new diff-functionality in ui-diff.c. Also added support for a path-parameter to filelevel diffs accessed via the diffstat. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
Diffstat (limited to 'ui-diff.c') (more/less context) (ignore whitespace changes)
