        * src/grep.c (prline): Simplifying rewrite using
          print_line_middle() and print_line_tail().  No longer attempts
          to find matches to colorize in context lines, thus avoiding
          costly calls to (*execute)(), since we know by then that they
          can't contain any by definition.  There are no longer four
          different code paths whether -o and -i are each specified
          or not; they have been unified into one, which should help
          avoid bugs similar to previous ones due to not updating all
          code paths in a synchronized fashion.  The -i code has been
          explicitly marked since it doesn't belong there and should
          be removed as soon as other -i code elsewhere is fixed.
          The remaining GREP_COLORS functionality is implemented.
          Savannah patch #3771 and patch #3644, heavily reworked.

Good design, done before coding, can usually structure things
(orthogonal modules) so that testing is a small project.

This is presumably the intent of unifying the four code paths into one.

          Add more tests, some initially failing.
