Subject: [PATCH] 	* cygpath.cc (main): Remove enforcing "en_US.UTF-8"
 locale. 	Revert usage of argz functions when reading input from file
 and 	simplify option usage.  Allow only one option argument and use 	the
 rest as filename argument to allow spaces in filenames.  Restrict 
 processing special folder type options to one line.
