comint-get-old-input (we're not looking at *old* input).
(comint-get-old-input-default): If using fields, signal an error
when the point is not in an input field.
(comint-mode-map): Reverse order of `comint-write-output' and
`comint-append-output-to-file'.
(comint-append-output-to-file): Reinstate this function, for the
benefit of the menu.
Fixup comint-last-input-end too.
Remove commented-out call to force-mode-line-update.
(comint-kill-output):
Use `forward-line 0' instead of beginning-of-line to make sure we get
past the prompt.
(comint-mode): Use define-derived-mode.
(comint-mode-map): Remove obsolete comment.
(make-comint): Minor stylistic change.
(comint-insert-clicked-input): Be more careful to find the overlay.
Use this-command-keys rather than hardcoding mouse-2.
Revert to using `insert-before-markers'.
Add bletcherous hack to undo damage caused by `insert-before-markers'.
Put `front-sticky' property on overlays created here so that the field code
understands how the overlay works.
Use a let when making comint-last-prompt-overlay, so that the code is
easier to read.
Compare end of comint-last-output-overlay with the start of the newly
inserted text, not the end, when deciding whether to extend it.
Set saved-point's insertion type to advance after insertion.
use save-restriction, now that it works correctly. Don't adjust
comint-last-input-start to account for our insertion; it shouldn't have
moved because we don't use insert-before-markers anymore. Comment out
call to `force-mode-line-update'; why is it here?
Use `insert' instead of `insert-before-markers'.
(comint-output-filter): Use `insert' instead of `insert-before-markers'.
Extend comint-last-output-overlay when necessary since we can't rely on
insert-before-markers to do it.
(comint-last-prompt-overlay): New variables.
(comint-output-filter): Implement prompt highlighting.
(comint-snapshot-last-prompt): New function.
(comint-send-input): Snapshot the last prompt.
Use comint-highlight-input-face.
(comint-highlight-input-face): Renamed from `comint-highlight-face'.
Use defface instead of defcustom.
(send-invisible, comint-send-eof): Snapshot the last prompt.
(comint-delchar-or-maybe-eof): Use comint-send-eof.
(comint-mode): Make `comint-last-prompt-overlay' buffer-local.
(comint-prompt-regexp, comint-get-old-input): Document dependence on
comint-use-prompt-regexp-instead-of-fields.
(comint-send-input): Add `input' field property to stuff we send to
the process, if comint-use-prompt-regexp-instead-of-fields is nil.
(comint-output-filter): Add `output' field property to process
output, if comint-use-prompt-regexp-instead-of-fields is nil.
(comint-replace-by-expanded-history)
(comint-get-old-input-default, comint-show-output)
(comint-backward-matching-input, comint-forward-matching-input)
(comint-next-prompt, comint-previous-prompt): Use field
properties if comint-use-prompt-regexp-instead-of-fields is nil.
(comint-line-beginning-position): New function.
(comint-bol): Use comint-line-beginning-position. Make ARG optional.
(comint-replace-by-expanded-history-before-point): Use
comint-line-beginning-position and line-end-position.
(comint-last-output-overlay): New variable.
(comint-mode): Make `comint-last-output-overlay' buffer-local.
(comint-read-input-ring): Doc change; use
comint-input-ring-separator when reading file.
(comint-write-input-ring): Use comint-input-ring-separator when writing file.
