I recommend dpkg --get-selections '*netscape*' instead. But the whole
bunch of 'informative' dpkg options is rather weird:
* dpkg --list doesn't list all available packages, but just the ones that
have been 'touched' by a selection. dpkg -- list '*' lists all available
and some unavailble (old cruft) packages. (not documented)
* same with dpkg --get selections. (not documented)
* dpkg -l '*netscape*' lists (on my system, continuously upgraded
since Debian 1.3) MORE packages than dpkg --get-selections '*netscape*'
but the difference is again never-installed cruft. (not documented)
* there is no obvious reason (except that the dpkg developers may have
more important things to fight with) why dpkg --status and
dpkg --print-avail shouldn't accept wildcards, too, but they don't.
