Fine except for "putting the text #if between single quotes".  We are
moving away from that convention.  Please take them back out again
wherever you added them.  If you like, you may take them out in all
the other messages in cppexp.c.  Then consider the patch approved.

If quotes are necessary for comprehension, use 'foo' not `foo'.  The
latter looks hideous with fonts where ' is vertical (increasingly
common).
