I tried to flet widen to ignore. That worked, but when trying to byte
compile I got:

  mumamo.el:6734:57:Error: Byte-compiling a redefinition of `widen'
will not work - use `labels' instead

But `labels' does a lexical binding, not a dynamic binding so that
obviously will not work. So now I don't know what to do...
defadvice...?
