My recommendation would be to look at the methods in the DJGPP port of GNU
'patch'. It has a similar dilemma (saving 'foo.c.orig' and possibly
'foo.c.rej' style files, within DOS 8.3 limitations), and IIRC, the
solution was rather thoughtfully set up by Eli, with some additional input
from me:

	foo.c.orig    becomes foo.c~
	foo.c.rej             foo.c#
	foo.bar.orig          foo.ba~
        foo.bar.rej           foo.ba#

(or something like that). Of course, every such pattern must break, in
some cases, like if you have two files named

	12345678.abc
        12345678.abd

or similar, i.e. full-length names, and the only difference in the very
position that would be replaced by '#' or '~'... But at least, it's 
trying to do as much as can.

Even if all the snow were burnt, ashes would remain.
