bug#6259: 24.0.50; `uniquify.el' advises `create-file-buffer'

[Drew Adams]

1. I thought that distributed Emacs code was not supposed to use
`defadvice'.  `uniquify.el' uses it.
 
2. That advice makes the doc for `create-file-buffer' incorrect:
 
emacs -Q
 
C-h f create-file-buffer RET
 
There is nothing about the function being advised.
 
Now turn on `Use Directory Names in Buffer Names' from the `Options'
menu.
 
C-h f create-file-buffer RET
 
You now see this added to the doc string:
 
 This function is advised.
 
 After-advice `create-file-buffer-uniquify':
 Uniquify buffer names with parts of directory name.
 
Now turn using directory names back off again, using the same menu item.
 
C-h f create-file-buffer RET
 
still says the same thing.  It _seems_ to be saying (and it will be read
this way) that buffer names are currently being uniquified with parts of
buffer names - which is incorrect.
 
3. Besides all that, "uniquify" is not a word (OK, in English anyone can
invent a word, but it is not a well-known term).  So any such doc should
be rephrased to say what actually happens to the buffer name.
