This helper function is intended to be used by callers implementing
--pretty themselves; it parses pretty.* configuration variables
recursively and hands the user-defined format back to the caller. No
builtins are supported, as CMT_FMT_* are really only useful when
displaying commits. Callers might like to define their own builtins in
the future.
