[PATCH v2 0/2] teach --only-matching to 'git-grep(1)'

[Taylor Blau <me@ttaylorr.com>]

Hi,

Attached is the second re-roll of my series to teach 'git grep
--only-matching'. Since last time, not much has changed. The change I
did include is summarized below, and an inter-diff is attached as
always.

  - Initialize both match_color and line_color to NULL, thereby
    silencing a compiler warning where match_color was given to
    opt->output_color uninitialized [1].

Thanks in advance for your review :-).


Thanks,
Taylor
