[PATCH] Do not limit git-version-gen to work only under the repository root.

[Giuseppe Scrivano]

Hello,

I would like to use git-version-gen from a directory that is not the
repository root, so "test -d .git" is not the proper check.

What about this patch?

Cheers,
Giuseppe

* build-aux/git-version-gen: Check if it is a git repository using the
"git status" command instead of test'ing the .git directory presence.
