On the BTS, you write:
Here it goes.
Just to note: I had to rename “diff.diffline” style to “diff.header” because
it makes sense to output _every_ header line bold (“diff...” line not being
something special) and this is how my patch works (this behaviour can be
easily reverted if you really don't like it for some reason).
Actually, no, I don't like it: I consider rolling unrelated changes
together like this to be bad engineering practice. Please send the fix
and only the fix, and leave all the other behavior and code and
formatting as constant as reasonably possible. Then feel free to follow
up with any other behavioral changes you'd like for separate discussion.
Otherwise, the patch looks pretty good except:

We don't like underscores in identifiers:

This is an unrelated change that introduces a dependency on Python 2.5.
This is a good example of why unrelated changes are bad: this change
could have easily slipped in and broken our next release for a bunch of
Py2.4 users with no upside. This sort of change also makes your patch
gratuitously more complex and thus harder to review.
Mathematics is the supreme nostalgia of our time.
