Actually, it's not necessarily the case that the problem occurs only
when there are a lot of output lines.  It happens sometimes and not
other times, but it's not clear to me what the criteria are.

Also, I can reproduce it with Emacs versions as far back as 24.1
(I haven't tried further back.  I think 24.1 is maybe when property
`compilation-message' was first introduced anyway.)
