pkgname_glob is one of these: a full pkgname, a pkgname w/o version,
a shell glob pattern in which you can use wildcards *, ?, and [..],
an extended regular expression preceded by a colon (:), or a date range
specification preceded by either < or >.  See pkg_glob(1) for details.
If none is given, all the installed packages are checked.
