[incremental] Patch: FYI: fix thinko in multi-hunk check

[Tom Tromey]

I'm checking this in on the incremental compiler branch.

This fixes a bug in the failure check for multi-hunk bindings.
The code was checking the wrong variable for the wrong value.

Also, this fixes a bad comment I noticed in c-tree.h.

With this patch, plus the ones from yesterday, I can now successfully
build GNU idutils, which is a multi-directory project.  This shows a
performance problem compiling regex.c :(, so I'll probably look at
that next.
