Subject: Possible kinder GIT-VERSION-GEN?
Message-ID: <18343.30080.67524.3427@lisa.zopyra.com>

I have my home directory under git control, and I have a build
directory (not tracked by git) under my home directory into which I
untar files and then in which I build things, including git.

When doing this, the version reported always contains the '-dirty'
suffix, which I find annoying (and potentially misleading).  I traced
this to the GIT-VERSION-GEN script, and I "fixed" it by checking
if there is a '.git' directory present before invoking git diff-index,
something like this:

dirty=$(sh -c 'test -f .git && git diff-index --name-only HEAD' 2>/dev/null) || dirty=
case "$dirty" in
'')
        ;;
*)
        VN="$VN dirty" ;;
esac

If someone of authority here thinks this seems reasonable (or has a
better way), I will test this (along with any suggested improvements)
with the git repo itself (to ensure it puts '-dirty' when it really
should), and submit a patch.
