test-highlight: unify normalization rule of pygments output

We had two variants for unknown reason, s/mf/mi/g and s/mi/mf/g. This patch
unifies them to s/mf/mi/g so that we can introduce a utility function.

from __future__ import absolute_import

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, globalvars)
        except Exception as inst:
            print(repr(inst))
