Subject: [PATCH] 	* prof_init.c (profile_init_path): takes a single
 string entry 	that has pathnames seperated by colons, and splits it into 
 file names for profile_init. No provision for quoting colons in 
 pathnames, but shells don't solve that either.

	* prof_init.c (profile_init): handle multiple input files by
	grabbing the first one that doesn't return ENOENT.
