bug#5264: 23.1; `repeat' should not hard-code the set of affected commands

[Drew Adams]

emacs -Q
 
In the definition of command `repeat':
 
(if (memq last-repeatable-command
    '(exit-minibuffer
      minibuffer-complete-and-exit
      self-insert-and-exit))
 
This list of affected commands should not be hard-coded.  If user code
uses different functions from `exit-minibuffer' and
`minibuffer-complete-and-exit', then users must redefine `repeat' to
accommodate this command difference.  The `repeat' definition should
be more flexible than that.
 
This list of commands should be treated the same way we treat the list
of dangerous commands (`repeat-too-dangerous'): define a variable
whose value is the list of commands - do not hard-code the list.
