```

On 32-bit platforms (only), gcc and sparse both issue warnings
about the type of the pointer expression passed as the third
argument to find_commit_header().  In order to suppress the
warnings, we simply change the type of the 'len' variable to
size_t.

Hi Jeff,

If you need to re-roll your 'jk/commit-author-parsing' series, could
you please squash this into the equivalent of commit 95b5989
("determine_author_info(): reuse parsing functions", 27-08-2014).

Thanks!

ATB,
Ramsay Jones

Thanks, this looks good to me. I think I just switched between size_t
and "unsigned long" during the development and forgot to tweak this
spot.

I don't think I have any other reason to re-roll at this point. I'm
happy to have this on top, or it can be squashed into the second from
the top (95b5989) if we want to keep the history cleaner.

I'm also happy to re-roll just for this, but my impression is that is
not really any easier on Junio than just squashing a patch in.

Thanks for being very considerate ;-)  Have squashed it in with
"rebase -i" while preparing for the mid-day pushout.
