bug#10463: 24.0.92; c-literal-limits out of range

[martin rudalics <rudalics@gmx.at>]

For quite some time, when editing c-mode buffers I get errors which
typically look like:

Debugger entered--Lisp error: (args-out-of-range 170988 178401)
   parse-partial-sexp(170988 178401)
   c-literal-limits(nil nil t)
   c-indent-new-comment-line(t)
   default-indent-new-line(t)
   do-auto-fill()
   apply(do-auto-fill nil)
   c-mask-paragraph(nil t do-auto-fill)
   c-do-auto-fill()
   self-insert-command(1)
   call-interactively(self-insert-command nil nil)

At this time the buffer is visibly narrowed - the arguments of
`parse-partial-sexp' were apparently within (point-min) and (point-max)
of the widened buffer but the second argument was likely after the end
of the the narrowed buffer.

Moreover, the buffer was no more associated with the file I was trying
to edit, so reverting the buffer was impossible, undo information had
been discarded, killing the buffer was possible without asking.
