Subject: 23.0.94; *compilation* long lines painfully slow

Guys, this is a follow-up to
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=2223.  It
might not have anything to do with that bug at all - I was just going
back and seeing if that bug had been fixed.

Create a Makefile with the contents:

all:
	@echo [insert 5000 chars]

Run emacs -Q and do Tools > Compile... RET and I see Emacs create the
*compilation* window and insert chunks of the echo output.  23.0.94
takes 20+ seconds to complete it and is pretty much unusable during that
time.  22.3 takes 1 second.  Looking back at earlier pretests, this also
applies to 23.0.91.

Thanks, Simon.
