Restrict login names.

There's no good reason to use an empty string as your login name, or to use one so long as to annoy others. Names beginning or ending with whitespace, or containing runs of whitespace, are also a technical problem, so they're also prohibited.

This change does not implement [UTS #39], as I haven't yet fully understood how to do so.
