 CVS code -
 - General:
 	- Miscellaneous comment fixes. (DLR)
-	- Don't allow filenames entered at the "Write File" prompt or
-	  the "Insert File" prompt to contain nulls.  Changes to
-	  do_statusbar_input(), do_statusbar_output(), and
-	  do_statusbar_verbatim_input(). (DLR)
 - files.c:
   do_insertfile()
 	- Properly handle executable commands that contain nulls. (DLR)
