Yeah.  I think they make the code harder to read.

I think "spec" and "as_default" don't add much value.  Then you would
have decode_line_with_current_source and
decode_line_with_last_displayed.  That is better but still on the long
side.  Perhaps "with" is also not needed.

Another approach would be to separate the defaults-getting from
decode_line in general.

This seems a little weird since this is already the default.
In a way this makes the "with_current_source_as_default" more confusing,
since that does not actually name the difference between this function
and decode_line_1.
