Fix a bug in StrFormat. This issue would have been caught by any compile-time
checking but can happen for incorrect formats parsed via ParsedFormat::New.
Specifically, if a user were to add length modifiers with 'v', for example the
incorrect format string "%hv", the ParsedFormat would incorrectly be allowed.
