RE: [cdt-dev] Error Parser Manager removes leading whitespace

["Pete MacLiesh" <pmac@xxxxxxxxxxxxx>]

It would actually be nice to eat continuations forwards rather than getting them one at a
time. We have a tool that pumps out dissertations like

Warning (TIE_WARN_UNUSED) foo.tie:27
    the dissertation starts
    here and goes on for
    several lines making the
    previous line alone not useful


So if an error parser could peek forwards and optionally eat continuations that would make
it more robust. Probably not easy the way it is stuctured as a stream though.

Ciao,
