xlint: fix bug in previous commit

In scan() I was using $argument in the sed script, but oftentimes
$arguments is a path including slashes which breaks havoc.

Different way now, hopefully this is correct now. Note that $msg has to
go through sed since some messages use `\2` to show the matching line.
