Logon group is also known as your current group.  When you logon or use
:chgroup
you have a logon group.  If you are in the PUB group and you :chgroup UTIL you
have changed your logon group (as well as your CWD) from PUB to UTIL.  We don't
keep track of your original logon group, just your current (logon) group. The
HOME group is not part of any POSIX rules (the SH UDC places your CWD to your
home group).  If your CWD <> logon group then we know that you have entered
the realm of POSIX, i.e., you have used the :chdir command or the >cd shell
command to move your CWD independent of your current (logon) group.

That is a common use of format 6 but my previous wrap around example applies
to format 6 .  E.g.,
:listfile ./,6
/HERE_IS_A/LONG_FILENAME/THAT_WILL/WRAP-AROUND/AND/YOU_CANNOT_TELL_THE/DIFFERNCE
/BETWEEN/THIS/AND/THAT
 
Now is this 2 filenames or just one that has wrapped?  The leading space makes
it unambigious.  (Or we could have indented that wrapped portion of the name,
but then we would need to know your terminal width, and we don't.)

No.  See above.
 
Hope this helps,
