Whoops!  No, this slowdown is caused by commit
89d1776b81ab552192ee41f13ce84ff86bda4556 on 2016-04-25, a fix for bug
#7918.  The bug was the spurious fontification of something like "for (;
a * b;)".

I'll see if I can find a better fix; if not, it would probably be best to
remove the commit and leave the bug unfixed.
