In principle, but that's the only place I'm seeing this.

I see it on every build I do (8 core machine, 16 threads, so I use
-j16).  And since the build is so nice and warning-free these days,
those messed-up lines stick out.

Unfortunately there's been other changes in these files, so the patch no
longer applies.  But I don't think it makes sense to work around this
problem by making the output look worse for most people, so I'd rather
just avoid using $(info) in the problematic parts -- then it'll look OK
for everybody (and without obfuscation).
