Ahh, well I sort of have a user "rooT" - I use hesiod over DNS for
passwd:

	alpha:src/bin/ps 14> host -c hs -t txt rooT.passwd.supp.cpr.itg.telecom.com.au.
	rooT.passwd.supp.cpr.itg.telecom.com.au descriptive text "root:xxxxxxxxxxxxx:0:1:Da Boss:/:/bin/tcsh"

It looks like the problem is in ps.c around:

    480         /*
    481          * if last letter is a 't' flag with no argument (in the context
    482          * of the oldps options -- option string NOT starting with a '-' --
    483          * then convert to 'T' (meaning *this* terminal, i.e. ttyname(0)).
    484          */
    485         if (*cp == 't' && *s != '-')
    486                 *cp = 'T';
    487         else {

And the fix will involve some of the logic from around line 503 as well.
I'll look into it further...
