This teaches the --color-words engine a more general interface that
supports two new modes:
* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}
* --word-diff=porcelain, which generates an ad-hoc machine readable
format:
- each diff unit is prefixed by [-+ ] and terminated by newline as
in unified diff
- newlines in the input are output as a line consisting only of a
tilde '~'
Both of these formats still support color if it is enabled, using it
to highlight the differences. --color-words becomes a synonym for
--word-diff=color, which is the color-only format. Also adds some
compatibility/convenience options.
Thanks to Junio C Hamano and Miles Bader for good ideas.
