RE: Killing/hiding functions

[Doug Lewan]

The most common way of disabling a function is to, well, disable it:

    (put 'ff-find-other-file 'disabled t)

This is unpleasant in the following way.
The function still exists and if you try to execute it you will get an error 
window.
(If you really never try to execute it, then that's not really unpleasant.)

To remove a function you can do this:

    (unintern 'ff-find-other-file)

This is dangerous.
1. The function no longer exists, so anything that uses it will probably not 
work any more.
2. Any variable of the same name no longer exists either.

I think this is easy if you know what you're looking for.

I'd like to hide, remove or un-name certain functions which I don't use,
so they don't show up when I do M-x, type some characters and then
TAB-complete.

For example, I'd like to have only one of the synonymous

  ff-find-other-file
  ff-find-related-file

And I'd like to forget visible-mode to have easier access to 
visit-tags-table.

What should I put in my ~/.emacs?
