* 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.
