List of possible coding systems

List of possible coding systems

[Stefan Monnier]

How about the change below ?
It removes `raw-text', `emacs-mule', and `no-conversion' from the
list of possible coding-systems to choose from (when prompting
the user during file-save) unless nothing else can be used.

I've found that people tend to misunderstand what those things
are and that such coding systems are only useful internally
or when used from elisp, but not as the coding-system
to use to save a given file.

Any objection ?

I have no objections in principle.  What does Handa think?

I think it's a good idea.  In select-safe-coding-system, now
one can select a coding system not listed.  So, removing
them won't cause a big problem.

If there's no objection, could you please install it?
