Bug 273472: ports-mgmt/pkg: running `pkg upgrade -` freezes pkg from
continuing, because of a missing char used for an option by accident

--- Description ---
Here is how it happened:

root@freebsd [~] # pkg upgrade -
Updating Local repository catalogue...
Fetching meta.conf: 100%    163 B   0.2kB/s    00:01	
Fetching packagesite.pkg: 100%	343 KiB 351.1kB/s    00:01

Local repository update completed. 1700 packages processed.
All repositories are up to date.
^C
root@freebsd [~] # pkg: archive_read_open_filename(-): Error reading stdin
pkg: No packages available to upgrade matching '-' have been found in the
repositories


I had to hit ctrl-c to get out of it, which shows pkg was confused that "-" was
a package name by that error message.
