I can't make this behave any differently than "finger 1@some.sunos.host";
it prints detailed info on all users who have a blank gecos field.  It
seems to fall into some code in finger that assumes that numbers are office
numbers (or building numbers or something) and throws them away.  Then it
takes the remainder (in this case, the null string) and prints all users
with matching gecos fields.
