It is usually has the format VERSION-REVISION.COMMIT, where COMMIT is
the first 7 characters of the commit id.  In this case the commit
summary would be:

  gnu: gmnisrv: Update to 0-2.32854b7.

If you use Emacs, there is a Yasnippet snippet for generating commit
messages in Magit, just type “update<TAB>” in the commit buffer.

I don’t use ‘gmnisrv’, so I can’t really test it, but it builds fine for
me.  :)
