[PATCH 0/4] Colouring whitespace errors in diff -B output

[Junio C Hamano <gitster@pobox.com>]

Here is a 4-patch miniseries to teach "diff -B" output routines to detect
and colour whitespace errors like we do for normal patches.

The first three patches are only about moving code around without changing
anything.

The last one hooks "diff -B" logic to the per-line output routines in a
way that mimicks how the normal patches are fed to them better, in order
to take advantage of all the existing whitespace error detection and
colouring logic.

Junio C Hamano (4):
      diff.c: shuffling code around
      diff.c: split emit_line() from the first char and the rest of the line
      diff.c: emit_add_line() takes only the rest of the line
      diff -B: colour whitespace errors
