Some distributions are using Git for part of their package management system, but unpack Git's own source code for delivery from the .tar.gz. This means that when we walk up the directory tree with git-describe to locate a Git repository, the repository we find is for the distribution and *not* for git-gui. Consequently any tag we might find there is bogus and does not apply to us. In this case the version file should always exist and be readable, as the packager is working from the released .tar.gz sources. So we should always favor the version file over anything git-describe guess for us. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
