Note: there are ugly bug (feature?) - when there isn't enought room for
whole double-width char two double-chars are displayed. Can be seen on
table with double-width chars reduced as much as possible.
Note: there is ugly hack in ACT_EDIT_BACKSPACE where last byte of UTF-8
character is removed and then moving to left until complete UTF-8
character is found.
Don't replace UTF-8 bytes with '*'. Probably there is need to do better
check what will be displayed.
Also get_current_link_title is no longer pretty and trivial. (o:
With UTF-8 support in terminal enabled it is possible to use double-width
UTF-8 strings as margins of buttons. Although they are displayed wrong when
UTF-8 support in terminal is disabled.
Preparation for using struct terminal in formating functions.
By now distinguish between formating widgets and formating widgets with
displaying was done with term == NULL and term != NULL. I hope I'am
not wrong.
This patch modifies ELinks wrapping behavior slightly.
* The wrap command now toggles line wrapping in HTML mode, as well as
text mode. Note that when the HTML view of a page is wrapped, its
source view is unwrapped, and vice versa.
* Tabs in text-mode lines are now handled correctly.
* Wrapping a line that reaches exactly to the edge of the screen will
no longer produce a blank line in text mode.
* Text within extra-wide table cells is now wrapped to less than the
screen width, to eliminate sideways scrolling.
The last point is only enabled by setting TABLE_LINE_PADDING to a
non-negative number, in the src/setup.h header file, because it is a
significant change of behavior from previous versions.
Use info_box directly instead of via report_scripting_error by way of
alert_smjs_error, thereby avoiding the addition of extra text saying
that an error has occurred.
Introduce the macros before_widgets and foreach_widget_back. Use the
latter in update_all_widgets instead of foreach_widget so that the
widgets are printed in reverse order, which means that any listbox is
drawn last, which allows it to grab the cursor from the selected button
when the dialogue box is initialised or redrawn.

With commit 637f1e82e6 ('NET: Merge
change_connection into cancel_download'), cancel_download returns
immediately if the connection is not in a result state, so save some
code by not checking is_in_progress_state before calling cancel_download.
Revert commit 2f0490cb04
('Eval embedded scripts at once') and follow-up commit
997f61bb32 ('Use document_view instead of
view_state. It is safer probably') because the change causes crashes on
numerous pages and just looks wrong.
