"correct" is a strong word when a particular behaviour of GAS involved. It
traditionally tried to follow the targets native assembler behaviour with
whatever quirks. In time it developed its own quirks and people came to rely
on
them. Nothing in that area is "correct" or "incorrect", it just is.
So, changing the assembler to have fewer quirks or have more
reliable or orthogonal behaviour needs to take the real world
into account, because that's where its raison d'etre is. If that means
adding hacks on top of the cleaner implementation (or moving them from
somewhere), then that is what needs doing. And if it means not even having a
cleaner implementation to start with, well, then that's the right solution :-/
(In this case, as you say, adding quirks is probably the right thing:
single-arg
macros consume everything until line-end (or whatever is was before),
and macro-arg prefix char consumes whitespace until identifier)
