[PATCH] git-version-gen: detect untagged revisions

[Mats Erik Andersson]

Hello there,

I have for some time been disturbed by the fact that 'git-version-gen'
relies on the presence of an annotated tag in order to pick a good
revision string.  The following patch is adding a mechanism to use
the call 'git describe --always' as the very last resort, in the
sense that it enters only if the fallback string is empty.

The addition of a leading 'g' to the revision hash is mostly a
convenience, but the usability of the patched version applied
to some cloned directory of small depth turned out more pleasant
than I had expected.

Best regards,
  Mats Erik Andersson, on behalf of GNU Inetutils
