makes more sense.  Also fixed bug in which the same Win32 directory
entered in different case would appear twice in the Directory Menu.
Added 'last entry' as default offering in the Change Directory
dialog much like the Run Command dialog already has.
The Clear History feature now additionally clears the
directory stack, the Change Directory 'last entry' buffer, as
well as the Directory Menu itself.
The directory menu logic now honors the MAXDIR option variable.
Fixed bug which left Command Menu enabled after reloading a
configuration file which had no commands defined.
All of the numeric options are now settable from within the
configuration file: DEBUGLEVEL, FSZ, HEIGHT, MAXDIR, MAXNESTING,
MAXHIST, REFRESHINT, and WIDTH.
