[PATCH] builtin/commit.c: fix type warnings from gcc and sparse

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

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
