I've been using comint a bunch recently and came up with a little tweak
to make input cycling with `comint-previous/next-input' more convenient.
Right now (24.1), if you scroll or search back a few elements in the
input history, there isn't, AFAICT, a keybinding for
`comint-restore-input'. Using 0 as a prefix argument gets you back to
history item 1, but overwrites `comint-stored-incomplete-input'.
I propose changing `comint-previous-input' so that it calls
`comint-restore-input' when called with 0 as its prefix argument. This
is merely a matter of inserting `(eq arg 0)' into the `or' conditional.
I doubt the current behavior (moving to history index 1 and overwriting
`comint-stored-incomplete-input') is something on which users are
relying. This would obviate the need for the user to create a custom
binding for `comint-restore-input'.
P.S. If anyone wants to use this behavior now, simply put this in your
init.el somewhere:
(eval-after-load 'comint
'(defadvice comint-previous-input
(around restore-comint-input-with-zero-prefix activate)
"Make `comint-previous-input' restore the input with arg == 0"
(if (and
comint-input-ring-index
comint-stored-incomplete-input
(eq arg 0))
(comint-restore-input)
ad-do-it)))
