Added document.cache.interval option. When time elapsed since previous access
to the document is less than interval then the document is taken from
the cache. Otherwise the request with filled "If-Modified-Since" and/or
"If-None-Match" header field is sent. By default interval is set to 10 minutes.
This requires the correct time to be set on your machine.
The current rules are:
term.utf8
CONFIG_UTF8 UTF-8 I/O widget_data.cdata
----------- --------- ------------------
undefined disabled charset of the terminal
undefined enabled charset of the terminal
defined disabled charset of the terminal (*)
defined enabled always UTF-8
(*) kbd_field was incorrectly assuming UTF-8 in this case.
This reverts the following commits:
- 86ed79deaf
Use wcwidth if available and applicable.
- 304f5fa1ea
comment fix (__STDC_ISO_10646__, not __STDC_ISO_10646)
- part of 71eebf1cc7
Compensate for glibc not defining wcwidth() when _XOPEN_SOURCE is not set
And adds a lengthy comment about LC_CTYPE problems.
Explicitly compare the value that is returned by the widget handler
against EVENT_NOT_PROCESSED rather than relying on the fact that
EVENT_NOT_PROCESSED is equal to 1.

ELinks currently fails this test. Also, it does not support all the
DOM features used here. I don't know whether the scripts should be
simplified or ELinks should be enhanced to support them.
The secure file saving code plays some shenanigans with the umask.
Previously, the code could fail to restore the old umask when certain libc
calls failed: malloc, mkstemp, fdopen, and fopen. This resulted in
unrelated code creating files with the wrong umode. Specifically, the
download code's automatic directory creation was creating directories
without the execute permission bit.
Thanks to Quiznos for reporting and helping to track the problem down.
To reproduce:
- Start ELinks.
- Enable the ui.tabs.wraparound option.
- Press t to open a second tab.
- Go to http://elinks.cz/ in the second tab.
- Press 3< to step three tabs to the left.
In the statement "tab = tabs + tab % tabs;", tab == -2 and tabs == 2.
So tab % tabs == 0 and tab becomes 2, which is out of range.
The new version calls get_opt_bool even if the tab parameter is already in
range, but the cost should be negligible compared to the redraw_terminal()
call that follows.
