Attached a new version of the patch: * It uses the default cutoff as max_width, whatever it is (as controlled by -fmessage-length). * It uses the pretty-printer. The text cannot (should not) wrap because we still print only max_width chars at most. * It removes unnecessary prune patterns.
Bootstrapped and regression tested with languages=all,ada,obj-c++.
Cheers,
Manuel.
