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.

def tryparse(text):
    r = {}
    try:
        r = pointer.deserialize(text)
        print('ok')
    except Exception as ex:
        print((b'%s' % ex).decode('ascii'))
    if r:
        text2 = r.serialize()
        if text2 != text:
            print('reconstructed text differs')
    return r
