[PATCHv2 0/3] grep color enhancements

This is a re-spin of the second half of Gmane 141186, "color enhancements, particularly for grep", which is currently in pu as 'ml/color-grep'. The following changes were made, all to the second patch:

* Fix the parsing of color.grep.  The old code caused a segfault if this
  option was set, and it also disallowed setting this option without
  a value.

* Color the filename in --name-only output.  I still don't like this,
  but I understand that makes the coloring more consistent.  As Junio
  said, if there's no strong argument one way or the other, it's
  probably best to follow GNU's lead.

* Style changes: Remove the cast to int for "rm_eo - rm_so", put else
  on same line as curly brace, and remove an unnecessary variable
  assignment.

* Asciidoc fixes: Use ";;" instead of ":::" for nested lists, and
  un-indent the last sentence for color.grep.<slot>.

Mark Lodato (3):
  Add GIT_COLOR_BOLD_* and GIT_COLOR_BG_*
  grep: Colorize filename, line number, and separator
  grep: Colorize selected, context, and function lines
