Set buffer-file-coding-system more sensibly with zero-length files.
lisp/ChangeLog addition:
2009-06-07 Aidan Kehoe <kehoea@parhasard.net>
* code-files.el (insert-file-contents):
Autodetection may return undecided as a coding system. If the file
was zero-length, this is kosher, and we should set
buffer-file-coding-system to its default; if it is not
zero-length, we still need to set b-f-c-s, but we warn that the
autodetection fails. (Ignoring that for the user, autodetection
failing is something very distinct from what we use it to mean
here.) See
http://mid.gmane.org/18986.53111.800393.660612@parhasard.net and
the related thread.

| 23 /* | |
| 24 * Radio.c - Radio button widget | |
| 25 * | |
| 26 * Author: Edward A. Falk | |
| 27 * falk@falconer.vip.best.com | |
| 442 | 28 * |
| 424 | 29 * Date: June 30, 1997 |
| 30 * | |
| 31 * | |
| 32 * Overview: This widget is identical to the Toggle widget in behavior, | |
| 33 * but completely different in appearance. This widget looks like a small | |
| 34 * diamond-shaped button with a label to the right. | |
| 35 * | |
| 36 * To make this work, we subclass the Toggle widget to inherit its behavior | |
| 37 * and to inherit the label-drawing function from which Toggle is | |
| 38 * subclassed. We then completely replace the Expose, Set, Unset | |
| 39 * and Highlight member functions. | |
| 40 * | |
| 41 * The Set and Unset actions are slightly unorthodox. In Toggle's | |
| 42 * ClassInit function, Toggle searches the Command actions list and | |
| 43 * "steals" the Set and Unset functions, caching pointers to them in its | |
| 44 * class record. It then calls these functions from its own ToggleSet | |
| 45 * and Toggle actions. | |
| 46 * | |
| 47 * We, in turn, override the Set() and Unset() actions in our own ClassRec. | |
