   Those patches were not meant to be posted.  I was replying to Brian, 
   and didn't notice the cc to gnu-bash-bug.  My apologies for any problems
   it may cause.  I'll be more careful in the future.  

   I'll look into the bug though.  Also, you can't do a macro bind to nil.
   It should give you an error for that.  If you want to disable a key, do 
   a function bind to nil (i.e. no "macro" keyword). 

When fully implemented, it won't give an error binding a macro to nil;
it will make a macro which produces "nil".  You might want to run New
Implementation of Lisp, you know.
