Message-ID: <20080104091613.GA7535@coredump.intra.peff.net>

```
The funcname patterns influence the "comment" on @@ lines of
the diff. They are safe to use with plumbing since they
don't fundamentally change the meaning of the diff in any
way.

Since all diff users call either diff_ui_config or
diff_basic_config, we can get rid of the lazy reading of the
config.

I am slightly worried that I'm missing something fundamental here. Why
were these ever lazily loaded in the first place? Ditto for the user
diff drivers, which should just get loaded when the command parses the
config for the first time.

Heh, I had a goofy diff.default.funcname option set up to test this out.
A slightly more readable version of the patch is below.
