The matched lines with warnings in the non-launcher compiler output in
CDash are already highlighted (bold) so maybe that much may already also
be possible with launchers?
I guess the launcher may currently quit looking after the first warning
but this would at least let me quickly find the first unsuppressed
warning in the output.

At least with the launchers, we'd be able to "scrape" from a single
output stream associated with a single build step and we wouldn't have
the mixing of lines problem anymore.
Nils has a point in that we are already analyzing the output
line-by-line in order to do custom warning suppression. It would be
awesome to make it better. (But would also probably require some
corresponding CDash changes...)
It's not going to be an "easy do it in a day" kind of thing, but this
is a good idea to keep on the back burner.
(Nils's main challenge at the moment, if I understand correctly, is to
find the ONE or TWO unsuppressed warnings in an output stream that
contains 100's of warnings... so that he can then suppress those as
well)

Limitations of that kind of "log scraping" was precisely the reason we
created CTEST_USE_LAUNCHERS in the first place. At most CTest should
add markup CDash can use to highlight unsuppressed warnings. That
way failure does not drop anything, messages are just less prominent.
