[S] Prevent infinite recursion with undecided coding system

[Michael Sperber]

Following Aidan's suggestion, this one uses Qbinary instead of
Qraw_text.

2007-07-31  Mike Sperber  <mike at xemacs.org>

	* file-coding.c (undecided_convert): Kludge to prevent infinite
	recursion.
	* file-coding.c (detected_coding_system): Change default from
	raw-text to binary.
