</span>Sadly, this is still a known problem and it got worse when we became<br>
more consistent about printing options for things like matrices and<br>
vectors (which rarely have prefixes and for which many options used to<br>
be hidden). Fixing it is somewhat at odds with our desire to remove<br>
global variables whenever possible, but I think it needs to be fixed. I<br>
tend to filter -help output with grep, FWIW.<br>
