pinky is in coreutils.

/usr/include/bits/utmp.h #define UT_NAMESIZE 32
but in w.c : 196
printf("%-9.8s%-9.8s", uname, u->ut_line);
which limits username (and terminal name)
to 8 chars, mayby I will ask procps maintainers.
This should be probably
printf("%-8s %-8s ", uname, u->ut_line);
Similary in line 211.

Not very pretty but there is no good way to do this prettier (mayby
first iterating over all entries and checking maximal widths, in second
use proper columns sizes).
BTW. Hostname is also truncated... which is also important for getXuser
functionality.
