[parted-devel] Avoid warning from -Wformat-security; tweak error diagnostic

[Jim Meyering]

FYI, I'll check this in early, tomorrow.

	Avoid warning from -Wformat-security; tweak error diagnostic.
	* parted/parted.c (_parse_options): Upon failure, output diagnostic
	to stderr, not stdout.  Use "program_name" value, not literal "parted".
