Preserv the current buffer on non-local exit, #'accept-process-output.
2015-03-31 Aidan Kehoe <kehoea@parhasard.net>
* event-stream.c (Faccept_process_output):
Restore the current buffer even on non-local exit in this
function, none of the code that uses #'accept-process-output is
actually prepared to handle the current buffer changing.

| 3094 | 32 ;; This file is totally bogus in the context of Emacs. Much of what it does |
| 33 ;; is really in the provice of faces (for example all the style parameters), | |
| 34 ;; and that's the way it is in GNU Emacs. | |
| 35 ;; | |
| 36 ;; What is needed for fonts at the Lisp level is a consistent way to access | |
| 37 ;; face properties that are actually associated with fonts for some rendering | |
| 38 ;; engine, in other words, the kinds of facilities provided by fontconfig | |
| 39 ;; patterns. We just need to provide an interface to looking up, storing, | |
| 40 ;; and manipulating font specifications with certain properties. There will | |
| 41 ;; be some engine-specific stuff, like the bogosity of X11's character set | |
| 42 ;; registries. | |
