diff: vary default prefix depending on what are compared
With a new configuration "diff.mnemonicprefix", "git diff" shows the differences between various combinations of preimage and postimage trees with prefixes different from the standard "a/" and "b/". Hopefully this will make the distinction stand out for some people. "git diff" compares the (i)ndex and the (w)ork tree; "git diff HEAD" compares a (c)ommit and the (w)ork tree; "git diff --cached" compares a (c)ommit and the (i)ndex; "git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity; "git diff --no-index a b" compares two non-git things (1) and (2). Because these mnemonics now have meanings, they are swapped when reverse diff is in effect and this feature is enabled. Signed-off-by: Junio C Hamano <gitster@pobox.com>
