(Parameter Access): frame-parameters arg is optional.
modify-frame-parameters handles nil for FRAME.
(Window Frame Parameters): menu-bar-lines and tool-bar-lines
are all-or-nothing for certain toolkits.
Mention parameter wait-for-wm.
(Frames and Windows): In frame-first-window and frame-selected-window
the arg is optional.
(Input Focus): In redirect-frame-focus the second arg is optional.
(Window System Selections): Mention selection type CLIPBOARD.
Mention data-type UTF8_STRING.
Mention numbering of cut buffers.
(Resources): Describe x-resource-name.
(read_avail_input): Change buf to pinter to read_avail_input_buf.
Use in_read_avail_input to handle re-entrance; when re-entered,
fully initialize and use tmp_buf array instead of read_avail_input_buf.
buf array was allocated on the stack.
(prev_read): Remove variable.
(read_avail_input_buf): New static event buffer array.
(in_read_avail_input): New static variable to avoid re-entrancy.
(read_avail_input): Change buf to pinter to read_avail_input_buf.
Use in_read_avail_input to guard against re-entry.
Do not initialize read_avail_input_buf here; instead assume it
is always cleared on entry. To ensure that, we clear (just) the
entries that were used before we return.
(init_keyboard): Initialize read_avail_input_buf here.
(rsf-min-region-length-added-to-spam-list): New variables.
(rsf-bbdb-auto-delete-spam-bbdb-entries): Renamed from
rmail-bbdb-auto-delete-spam-entries. Added cc: to recipients for
spam testing. Don't delete spam message if automatic deletion
after output via variable rmail-delete-after-output is turned on.
(rsf-bbdb-dont-create-entries-for-deleted-messages): Renamed from
rsf-bbdb-dont-create-entries-for-spam.
(check-field): New function, extracted from code in
rmail-spam-filter to ease addition of header fields like
content-type.
(message-content-type): New variable to check the content-type:
field added, also in defcustom of rsf-definitions-alist.
(rmail-spam-filter): Replace repeated test code for header fields
by calls to check-field; change the call to
rmail-output-to-rmail-file such that rmail-current-message stays
the same to avoid wrong deletion of unseen flags.
(rsf-add-contents-type): New function to convert old format
of rmail-spam-definitions-alist into new one.
Changed prefixes of all variables and functions from
rmail-spam-filter- or spam-filter- or rmail-spam- to rsf-.
