ATM we capture each Warning (or error) with the following regexp:
"^.*+?\\(?:Error\\|Warning\\): .*$"

So I expect we match the full line (if is a multi line diagnostic we'll
loose what's following).

The matched string is passed directly to `display-warning'.  I don't
know if we have same machinery cutting lines that are considered too
long.

Thanks
