log: display closing-branch nodes as "_" (BC)

In plain `hg log` there is no indication that a commit closes a
branch. You can use hg log --debug, but this is too verbose. A simple
idea copied from thg and other graphical viewers is to display the
node for a closing-branch commit as a horizontal line.

I think this technically is a BC if we consider the graphlog to be
part of the stdout API, but I really can't imagine who the hell is
parsing the graphlog to determine information about commits.

import sys

globalvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print l[:-1]
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            exec c in globalvars
        except Exception, inst:
            print repr(inst)
