JHT ===> William Yost patches integrated to fix leading path on 8.3

filename problem.
	Problem conditions:
		case sensitive = no
		default case = lower
		mangle case = yes
		preserve case = yes
		short preserve case = yes
	Problem: Win95 still writes upper case file names.
	Patches supplied have been incorporated into mangle.c and server.c
	but needs YOSTW to be defined for it to take effect.

	Action:
	=======
	If we are happy with the patch, delete old code in mangle.c, then
	remove all YOSTW #ifdefs.
(This used to be commit 84fc674c89)
