corrections (typos, style, command revisions, etc).
Integrated hacked up XEmacs immediate keybindings display. See
`icomplete-show-key-bindings', `icomplete-get-keys', and
`icomplete-completions'. Doesn't work with mainline GNU
Emacs 19.34 (because the cmdloop doesn't set owindow, and the
current-local-map doesn't take optional buffer arg), so feature
is, by default, inhibited unless we're running in XEmacs.
(icomplete-get-keys): Return keys bound to func name in buffer
"owindow" - since "owindow" is calling-buffer history present
only in XEmacs, this function is only useful in XEmacs.
(icomplete-max-delay-chars, icomplete-compute-delay): New vars.
(icomplete-delay-completions-threshold): New var.
These customize the delay behavior, so that completions don't
intrude as quickly for short input.
Doc fixes.
(icomplete-mode): New function and var.
(icomplete-minibuffer-setup-hook): New hook.
(icomplete-inhibit): Defunct. Using icomplete-pre-command-hook,
icomplete-post-command-hook as real hook functions.
(icomplete-simple-completing-p): Subsumes
icomplete-window-minibuffer-p plus other stuff, determines whether
simple completion is active.
(icomplete-window-minibuffer-p): Defunct, see above.
(icomplete-minibuffer-setup): Use icomplete-simple-completing-p,
copy-sequence hooks before adding to them, run hooks properly.
(icomplete-tidy): Changed from misnamed icomplete-pre-command-hook;
use icomplete-simple-completing-p.
(icomplete-exhibit): Changed from misnamed icomplete-post-command-hook;
use icomplete-simple-completing-p.
(icomplete-completions): Changed from old, misnamed icomplete-exhibit;
combined with old misnamed icomplete-prompt.
(icomplete-post-command-hook): Likewise.
(window-minibuffer-p): Cleaned up according to suggestion from
Richard Mlynarik.
General rectification of doc strings and comments.
