Hi!  I created a new copy of cc65's CBM library's cbm_dir.c file specifically
for DirMenu and optimized it.  Mainly, I disabled some code I didn't need. 
Now, all DirMenu binaries fit in a comfortable six blocks.  I just uploaded
them to https://
sourceforge.net/projects/harryp-cbm/files/c64/ui/ and
https://sourceforge.net/projects/harryp-cbm/files/c128/ui/.  Try them!  :)
