bug#17902: 24.4.50; (elisp) `Function Debugging' still says redefining a function cancels `debug-on-entry', which is no longer true

[Drew Adams]

I guess this text too needs updating (?), in node `Debugger Commands':

`l'
     Display a list of functions that will invoke the debugger when
     called.  This is a list of functions that are set to break on
     entry by means of `debug-on-entry'.  *Warning:* if you redefine
     such a function and thus cancel the effect of `debug-on-entry', it
     may erroneously show up in this list.

And again, the last sentence (which might need updating) should not be
shown as a WARNING. There is no danger to warn of.  It is simply a note.
