Finished sorting logic. Fixed bug with Win32 case collapse. ...

Changed arithmetic in poll() which sets reduced period for
next refresh if a locked mutex is encountered.

Changed SORTBYFIELD to be the *name* not the number of the field desired. ...

Check SORTBYFIELD to see if it makes sense.  If not, it is hardwired to fNAME.

Keyboard support and title bar display for sorting implemented.

More work on sorting.

MAXDIR, MAXDIRBUF, MAXHIST, MAXHISTBUF have been retired in favor of MAXMENU and
MAXMENUBUF which are common parameters for all dynamic menus.

both accelerator key and mouse/key combo to popup that menu.

Program Function Key handlers now return 'break' consistently
to make sure a user key rebinding does not conflict with some Tk default.
Back to displaying full version number or Titlebar.

Document fix for CMDSHELL processing of User-Defined Commands.

Changed logic so CMDSHELL processing, if enabled, is *only* ...

done when KeyRunCommand is invoked via the RUNCMD key - i.e,
Not when commands are played back via the Command History
Mechanism.  This is a cleaner way to prevent CMDSHELL cascading
on history invocations and also fixes a bug wherein a Command
Definition would get processes with CMDSHELL if that command
was replayed from the history.

Integrated Haggard's comments.
