make last_point invalid instead of setting it normally.
(display_text_line): If cursor's in the frame's echo area,
don't set this_line_endpos.
(redisplay_window): Use Fwindow_end to find lower scroll margin.
(init_kboard, command_loop_1): Init Vlast_prefix_arg.
(Fcommand_execute): Set Vlast_prefix_arg to prefix arg used.
(command_loop_1): Set Vreal_last_command with Vlast_command.
(init_kboard): Init Vreal_last_command field.
(syms_of_keyboard): Set up Lisp var real-last-command.
(lispy_function_keys): Add kanji...eisu-toggle.
(re_match_2, re_search_2): Adjust startpos or pos by 1
only if acting on a buffer.
nil for re_match_object means a buffer.
(re_match_2_internal <notwordbeg>): Assume POS1 is positive.
that ends a comment, when moving forward.
(Fbackward_prefix_chars): Return immediately if point is at BEGV.
(prev_char_comend_first): New function.
(back_comment): Use that. Carefully update syntax table position
for each character that is fetched.
(Fforward_comment): Likewise.
(scan_lists): Likewise.
(prev_char_comstart_first): New function.
(sys_access): Provide our own implementation which recognizes D_OK.
(is_exec): New function.
(stat): Use it.
(init_environment): Set TMPDIR to an existing directory.
Abort if none of the usual places is available.
(sys_rename): On Windows 95, choose a temp name that
includes the original file's base name and use an explicit loop
rather than calling mktemp. Only attempt to unlink the newname if
the rename fails, rather than second-guessing whether the old and
new names refer to the same file.
for a string.
(interval_start_pos): New function.
(find_interval): Handle string positions starting at 0.
(adjust_intervals_for_insertion): Likewise.
(adjust_intervals_for_deletion): Likewise.
(compare_string_intervals): Likewise.
(graft_intervals_into_buffer): Set `position' in reproduce_tree value.
(copy_intervals): Init `position' to 0.
(prev_saved_doc_string*): New variables.
(Fload): Initalize prev_saved_doc_string.
(read1): Copy saved_doc_string to prev_saved_doc_string
before storing a new string in saved_doc_string.
(read_list): Look in prev_saved_doc_string as well as
in saved_doc_string.
(read1): Swap saved_doc_string_length and
prev_saved_doc_string_length.
(read_list): Negate docstring position if negative before checking
against saved_doc_string_length et al.
(read_vector): Add bytecodeflag parameter, which is
nonzero when reading a bytecode object. If
`load-force-doc-strings' is t when reading a lazily-loaded
bytecode vector, the loaded docstring must be treated as unibyte
and passed to Fread to obtain the actual bytecode string and
constants vector.
(read1): Add extra parameter to read_vector calls.
(read1): Enable saving of doc strings on WINDOWSNT.
(read_list): Call get_doc_string instead of read_doc_string, when
forced to load doc strings.
position for string when comparing with LIMIT.
(property_change_between_p): Likewise.
(Fnext_single_property_change, Fprevious_property_change): Likewise.
(Fprevious_single_property_change): Likewise.
