histedit: render a rolled up description using the proper roll colours

Users have rightfully complained that the old behaviour of completely
removing the description of a rolled commit makes it difficult to
remember what was in that commit. Instead, we now render the removed
description in red.

I couldn't think of a simpler way to do this. You can't just combine
existing curses colours into new effects; only secondary effects like
bold or underline can be logically OR'ed to generate a combined text
effect. It seems easier to just redundantly keep track of what the
roll colour should be.

#require no-pure

A script to generate nasty diff worst-case scenarios:

  $ cat > s.py <<EOF
  > import random
  > for x in range(100000):
  >     print
  >     if random.randint(0, 100) >= 50:
  >         x += 1
  >     print(hex(x))
  > EOF

  $ hg init a
  $ cd a

Check in a big file:

  $ "$PYTHON" ../s.py > a
  $ hg ci -qAm0

Modify it:

  $ "$PYTHON" ../s.py > a

Time a check-in, should never take more than 10 seconds user time:

  $ hg ci --time -m1
  time: real .* secs .user [0-9][.].* sys .* (re)
