bug#12046: 24.1.50; Regression: command `ucs-insert' is no longer recognized

[Drew Adams]

It's one thing to want to alias `ucs-insert' to `insert-char' or vice
versa.  It is another thing to simply remove `ucs-insert' as a command.
 
That is not kosher.  That is not deprecation - it is immediate
desupport.  Please restore `ucs-insert', at least as an alias, so that
users and code that calls `ucs-insert' do not find themselves orphaned.
 
Furthermore, I see this in NEWS:
 
** `insert-char' is now a command, and `ucs-insert' an obsolete alias
for it.
 
No, the latter part is apparently not true.  Neither `M-x' nor `C-h f'
recognizes `ucs-insert' at all.

I also do not understand this, which is the only occurrence of `ucs-insert' in
the distributed Lisp files:

(define-obsolete-variable-alias 'ucs-insert 'insert-char "24.2")

What is that about?  Variable?  Seems like this is the cause of the bugged
behavior: the function no longer exists.
