Treat `-T's optional argument as optional
`-T[format]' is not possible with getopt(3) but getopt_long(3) supports "T::" exactly for that, so make the command line option go in line with configuration files and documentation. While here, check `has_arg' explicitly as getopt_long(3) only documents mnemonic values not numerical ones.
