* if run by root (or root process) drop privs
* ensure output size is not infinate (net finger only)
* ensure output lines are not infinate in length (net finger only)
* do not allow finger client to run longer than 3 minutes (net finger only)
implementations to leave the client side open until the server closes.
While this is totally idiotic, it seems as if some servers actually require
it (e.g., the one at mit.mit.edu). So, we bow to the weight of the bogus
standard and disable the initial close. Hopefully now fetch(1) can serve
the role of T/TCP demonstration application.
finger output from 80 to 79 characters to stop the syscons
every-second-line-is-blank problem.
Also, redo the TTY column mod so that it steals one of the (usually) two
blank spaces from the before the tty column rather than from the office
phone number.
This means the office phone field width in the short finger is back to 15
characters instead of 13.
This gives us more room to breath with tty names, especially with drivers
that support large numbers of ports.. eg: specialix and digiboard.
This does not actually change the current tty names, it just allows room
for reporting more characters if the drivers use them.
By default, behave like the old ugly 4.4bsd finger and print office
information instead of remote login information.
It's an easy one line fix to make it behave like most other vendor's
fingers if we decide to change the default.
