Hmm, I would have expected:

.loc [FILE LINE [COLUMN]] [basic_block] [is_stmt [VALUE]]

et cetera.  I think it's still unambiguous.  The chattier we make these
things, the longer it'll take to assemble them... but probably not a
big deal.



I suppose that's possible as well, yes.  I hadn't liked that because
it makes the column number non-optional, but having the user add the
one zero is not that big a deal.


I must be missing something.

Why would the column number be non-optional?
