Subject: [PATCH] refs.c: remove extern keyword from function definition

Commit 5ed85684 ("reflog_expire(): new function in the reference
API", 12-12-2014) added a new function definition which included
the extern keyword.

While this is not an illegal use of the keyword, it is somewhat
unusual to include it in a function definition. (It would be
unique in the git codebase). Also, it triggers a warning from
sparse. In order to suppress the warning, simply remove the
extern keyword from reflog_expire() definition.

Hi Michael,

If you need to re-roll your 'mh/reflog-expire' series, could you
please squash this into the relevant patch.

Thanks!

ATB,
Ramsay Jones

Thanks for spotting this! It looks like Junio has already squashed this
commit into place in the "pu" version of my branch. So thanks Junio, too!
