The gettext .po files have a header, but it looks like the translation
specification for an empty string. This results in _("") actually
returning that header.
Prevent parseopt from passing empty strings to gettext when it
displays help about commands. In some instances it already did this,
but git-grep's --or etc. caught another case.
