Re: git-version-gen: add support for empty release commits

Hi Dmitry,

It does care during "git rebase -i".

Ah, thanks! I didn't know about this difference. The manual page [1] explains
it:

  "Annotated tags are meant for release while lightweight tags are meant
   for private or temporary object labels. For this reason, some git commands
   for naming objects (like git describe) will ignore lightweight tags
   by default."

I've changed the my gettext tag from a lightweight tag to an annotated tag,
and "git describe" now behaves as expected.
=> No need to change the git-version-gen script.
