ut_id questions

[Daniel Jacobowitz <drow@false.org>]

There seems to absolutely no convention for what values to put in
ut_id in the presence of /dev/pts.

In a quick survey, ssh uses the last two characters of ut_line;
bsd-style login uses everything after the fourth character (which
happens to be the /); telnetd uses everything after the third character
(thus beginning with the /).  PAM uses the last four characters.

Are any of these 'right'?

Also, utmp(5) claims that the ut_id should be 'p' followed by the
number - which seems like a really bad idea, since ttyp0 and pts/0
would then have the same ut_id.
