There are several uses I can think of:

	1) linking: cd /etc; ln passwd PASSWD
		This makes it less likely that I will lose my passwd
		file even if I do `rm p*'.
	2) old versions: cd /etc; cp passwd PASSWD
		Keeps a backup version. Note that these two uses may
		conflict if I decide to `cp /dev/null PASSWD'!
	3) filename completion: using (1) an the 4.3 csh, I can type
		`vi /etc/P<ESC><RET>'. Ok, ok, emacs then :-)
	4) intermediate files: instead of picking a new name, I can
		just change case. Yes I know I can use other methods.

While I generally think it undesirable to depend on case for human 
distinction, it comes in quite handy sometimes. I have seen the same
trick used in C programs as well, #defining foo to union_name.Foo.
Before you flame the usage, my source is the Berkeley VLSI tools.
