I just sent a patch to put the funcname pattern in the "basic" config,
and to get rid of the lazy config loading. So that fixes one call by the
plumbing to read_config_if_needed.

And it looks like the second call is already OK. We don't try parsing
the config to get the external diff command unless ALLOW_EXTERNAL is
set, which the plumbing already disallows (though I am still confused
why it would need to be loaded lazily in the first place -- I wonder if
read_config_if_needed is needed at all).
