(undo-copy-list, undo-copy-list-1): New functions.
(undo-make-selective-list, undo-delta): New functions.
(undo-elt-in-region, undo-elt-crosses-region): New functions.
(undo-adjusted-markers): New defvar.
(undo-start): New args BEG and END.
(undo): If arg or active region, pass args to undo-start.
(set_internal, default_value, Fset_default, Fmake_local_variable)
(Fmake_variable_buffer_local, Fkill_local_variable):
Handle new data structure for struct Lisp_Buffer_Local_Value.
(Fmake_variable_frame_local): New function.
adjust_overlays_for_delete.
(adjust_after_replace): Delete args COMBINED_BEFORE_BYTES and
COMBINED_AFTER_BYTES. This makes the newly generated text
following GPT_ADDR a buffer contents.
and handling post-read-conversion here, they are done in
code_convert_region. Even if a file is read by no-conversion,
call adjust_after_replace to adjust positions.
(insert_1_both, insert_from_string_1, insert_from_buffer_1):
Simplify greatly by using combine_bytes near the end
to handle all aspects of combining except for undo-recording.
This means most of the code deals with the text as if there were
no combining.
(replace_range): Likewise. Also handle unibyte-multibyte conversion
as in insert_from_string_1.
(del_range_2): Handle combining of character before the deletion
with strays after the deletion.
(adjust_markers_for_delete): Delete debugging code for Z == Z_BYTE.
(adjust_markers_for_insert): Move Z == Z_BYTE debugging code
to before we relocate the marker.
the combined_after_bytes. Use DEC than INC when leaving
a marker before the insertion.
(count_combining_before): Return number of bytes from start
of insertion that will combine.
(insert_1_both): Compensate for change in count_combining_before.
Delete intervals for the combined_after_bytes.
Compensate for that when updating other intervals.
(insert_from_buffer_1, replace_range): Likewise.
(adjust_after_replace): Likewise.
(insert_from_string_1): Likewise. Also handle intervals
for inserting just part of string.
(scheme-font-lock-keywords-1, scheme-font-lock-keywords-2,
scheme-font-lock-keywords): Moved here from font-lock.el.
(dsssl-mode): Move font-lock-defaults setting and running hooks.
(hippie-expand-dabbrev-as-symbol): Renamed `he-dabbrev-as-symbol'.
(hippie-expand-no-restriction): New variable.
(hippie-expand-only-buffers): New variable.
(he-init-string,he-line-search,he-list-search,he-dabbrev-search): Use
`buffer-substring-no-properties' to avoid transfer of text properties.
(he-dabbrev-kill-search,he-whole-kill-search): Remove text properties
from search result.
(he-regexp-member): Removed function.
(he-buffer-member): New function used instead of `he-regexp-member'.
(try-expand-line,try-expand-line-all-buffers,try-expand-list,
try-expand-list-all-buffers,try-expand-dabbrev,
try-expand-dabbrev-all-buffers): Depending on
`hippie-expand-no-restriction', widen the buffer before search.
(try-expand-line-all-buffers,try-expand-list-all-buffers,
try-expand-dabbrev-all-buffers): Use `he-buffer-member' and
`hippie-expand-only-buffers'.
