commit 1846620b54d5075295dc1c5c3d89fa2bad95ea82
Author: Elliot Lee <sopwith src gnome org>
Date:   Tue Dec 23 03:46:26 1997 +0000

    Hmm, some moron (me) added all the test suite binaries to CVS, must
    fix that.
    
    What I actually did:
    	. Added gnome_chomp_string
    	. Filled in the TODO list a bit more.
    	. Coded the gnome_recently_used stuff from the TODO list
    	  (it's theoretically beautiful, but needs testing beyond
    	   compilation :-)
