+0 on this: it doesn't really add anything, but it does neaten things
up.

+1 here too: this definitely adds utility.

-0: adds nothing, cleans nothing up, and just generally breaks things
for no good reason.

OK, that's a good reason.  Maybe you could special-case the "<stdin>"
case?  How about

   <stdin>, line 1

?
