gettext: do not translate empty string 

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.

Check the input to _() and do not call gettext() on an empty string;
in some places, we run _(opts->help) where opts->help may be empty.
