Re: comint-dynamic-list-input-ring should be dedicated

[Richard Stallman]

    * emacs -q --no-site-file
    * M-x shell
    * C-c C-l
    * Change to input history window
    * choose an entry

    The buffer in the second window (input history) is buried cause it's
    not dedicated (i hope this is a correct interpretation...) and the
    frame contains two windows after choosing the completion.

This is how the input history feature works: when you select an
element from the input history, the input history disappears.

Why is this a problem?
