Re: [RFC PATCH] Fix gitdir detection when in subdir of gitdir

Thanks.  In the meantime I was working on a patch that sets relative
path in this case, too.

Does it make sense to use relative path in such a case?

If it is for "rev-parse --git-dir", the calling script may learn the
correct location of the GIT_DIR with either relative or absolute, but if
it is for the internal consumption of git process itself and any
subprocess forked from us that look at GIT_DIR we export, the process
already runs at the repository root (because you do not chdir back) and
using relative path does not make much sense.  Exported GIT_DIR has to be
either "."  or the full path from the root to make sense to such a user, I
think.
