Subject: gitk: Use the --submodule option for displaying diffs when available
X-Git-Tag: v1.6.6-rc2~2^2~9
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/5c838d23aa02476cfe91b0eea047b6d5857da770?ds=inline;hp=5c838d23aa02476cfe91b0eea047b6d5857da770

gitk: Use the --submodule option for displaying diffs when available

When displaying diffs in a submodule, this makes gitk display the
headlines of the commits being diffed, instead of just showing
not-quite-helpful SHA-1 pairs, if the underlying git installation
supports this.  That makes it much easier to evaluate the changes, as
it eliminates the need to start a gitk inside the submodule and use
the superprojects hashes there to find out what the commits are about.

Since the --submodule option of git diff is new in git version 1.6.6,
this only uses the --submodule option when a git version of 1.6.6 or
higher is detected.
