(Finsert_file_contents): Save and restore errno,
so that report_file_error outputs the correct diagnostic.
(Fwrite_region) [CLASH_DETECTION]: Likewise.
src/bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
(bidi_find_paragraph_start): Search back for paragraph beginning
at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
(bidi_move_to_visually_next): Only trigger paragraph-related
computations when the last character is a newline or at EOB, not
just any NEUTRAL_B.
src/xdisp.c (reseat_at_next_visible_line_start): Keep information
about the current paragraph and restore it after the call to
reseat.
(cons_to_x_long): New function.
(lisp_data_to_selection_data): Use it. Correct the test for
short-versus-long data; it was negated. Break out of vector
loop, for efficiency, when a long datum is discovered.
src/xterm.c (x_draw_composite_glyph_string_foreground):
src/w32term.c (x_draw_composite_glyph_string_foreground):
src/term.c (encode_terminal_code):
src/composite.c (composition_update_it, get_composition_id):
src/xdisp.c (get_next_display_element)
(fill_composite_glyph_string): Add comments about special meaning
of TAB characters in a composition.
Patch by Johan Bockgוrd <bojohan@gnu.org>
src/xdisp.c (try_cursor_movement): Only check for exact match if
cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
(selection_data_to_lisp_data): Assume incoming selection data are
signed integers, not unsigned. This is to be consistent with
outgoing selection data, which was modified to use signed integers
in as part of the fix to Bug#9196 in response to Jan Djärv's comment
in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
expects long, not unsigned long.
src/fileio.c (Finsert_file_contents): If the file cannot be opened,
set its "size" to -1. This will set the modtime_size field of
the corresponding buffer to -1, which is what
verify-visited-file-modtime expects for files that do not exist.
here ...
* lisp.h: ... from here. push_key_description is no longer
defined in keyboard.c, so its declaration should not be in
lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
logically belongs with push_key_description.
* window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
Operate on live windows only.
* window.el (window-deletable-p): Make sure window is live before
invoking window-prev-buffers.
Without this fix, the command to link temacs failed due to an
undefined symbol __builtin_isnan. This is because
/usr/include/iso/math_c99.h #defines isnan(x) to
__builtin_isnan(x), but the bundled gcc, which identifies itself
as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
a __builtin_isnan.
* configure.in (isnan): Remove now-unnecessary check.
* src/floatfns.c (isnan): #undef, and then #define to a clone of
what's in data.c.
(Fisnan): Always define, since it's always available now.
(syms_of_floatfns): Always define isnan at the Lisp level.
