casefix Version 1.1

[Jeff Beadles]

Well, there was a bug on some systems with the original version of casefix that
I posted last week.  Some system's don't handle toupper/tolower properly if the
character is not alpha to be begin with.  So, I've changed things like
	ch = tolower(ch) to...

	if (isupper(ch))
		ch = tolower(ch);

Also, I've added the provision for '\n\n' to also be considered the end
of a sentence.

I decided not to post a patch, as the entire source listing is <5k.


Have fun, and remember to always post follow-up's to alt.sources.d :-)
