Infinite loop in C-x 4 a from C buffers

[Stefan Monnier]

Try the following:

  emacs -Q src/lisp.h
  C-s Fplist_put RET
  C-x 4 a

you should see Emacs get stuck in an infinite loop (not a bad, one: C-g
stops it just fine).

PS: BTW, am I the only one who experiences odd slowdowns when editing
src/lisp.h, apparently due to font-lock occasionally taking a lot of time
(like a second or two) to do its job.  Not easy to reproduce, sadly.
