using gitinfo2 within a git submodule

[anbe42]

Hi,

gitinfo2 does not work if the repo is a git submodule, because the .git directory is located elsewhere (in the parent repo), referenced in a .git file as e.g. gitdir: ../.git/modules/my.submodule

For the hook script it is easy to find the correct GIT_DIR: git rev-parse --git-dir

For the style it is more complicated to do this ... I only implemented a proof-of-concept solution that works for building within the root of the submodule, it does no search through the parent directories. The tex part could surely be improved :-)
I haven't even thought about how this should work for nested submodules.
My preliminary patch is attached.

PS: Another hint: The no-op command I use for updating gitHeadInfo.gin (especially refreshing dirty state) is git checkout (it does not change the repo, even if something is staged/uncommitted, but it runs the hooks)), integrated somewhere in my Makefile based build system.
