[PATCH v2 0/6] Teach '--column-number' to 'git-grep(1)'

[Taylor Blau <me@ttaylorr.com>]

Hi,

Attached is a re-roll of the series to add --column-number to
'git-grep(1)'.

Since last time, I have changed the following (an inter-diff is
available below for easier consumption):

  * Removed '-m' as an alias for '--column-number', per René's
    suggestion [1].

  * Fix some incorrect spelling of 'columnnumber'.

  * Change casing of 'color.grep.linenumber' to 'color.grep.lineNumber'
    to be consistent with 'color.grep.columnNumber'. This is an
    unrelated change, and one which I am happy to drop from this series.
    It was suggested by Martin in [2].

Thanks in advance for your second round of review :-).


Thanks,
Taylor
