23.0.60; M-( and M-) should not be bound in ESC map

[Drew Adams]

This bug is not new.  M-( and M-) are bound in `esc-map', which means
they are in effect pretty much everywhere, including the minibuffer.
 
This is is not a good idea.  `insert-parentheses' and
`move-past-close-and-reindent' should be bound only for programming
modes for which they actually make sense.  
 
It can be surprising to get an error "Unbalanced parentheses" 18,
5795" or "Containing expression ends prematurely" or some such if you
accidentally hit M-) in the minibuffer or a text file. This is the
kind of thing that can frighten users unnecessarily.
