$(AM_CFLAGS) is one of the variables set by Automake, which ELinks no
longer uses. $(CPPFLAGS) should be used whenever the C preprocessor
is run, according to the GNU Coding Standards. (My build environment
does have an important -I option there.)
... since the latter is for printing int64_T and we don't check for that and
we use PRId64 only for printing values having the off_t types.
Besides off_t has it's own ELinks specific defaults so it should be safer
to use an internal format string. If off_t is 8 bytes use "lld" else use
"ld".

Drop some code for superscript and subscript handling that was deleted
in commit 65016cdca4, then added back
with the UTF-8 merge in commit 2a6125e3d0,
and then disabled in commit 1b653b9765.
Also list the capnames with which the escape sequences could be
read from Terminfo, and the ECMA-48 interpretations of the bytes
(parenthesized if they seem unrelated to the keys). This is in
preparation for fixing bug 96.
decode_terminal_escape_sequence() used to handle both, but
there is now a separate decode_terminal_application_key()
for ESC O. I have not yet edited decode_terminal_escape_sequence();
there may be dead code in it.
If there is e.g. ESC [ in the input buffer, combine that to Alt-[.
Check the first character too; don't blindly assume it is ESC, as
it can be NUL as well. Note this means you can no longer activate
the main menu by pressing Ctrl-@ (or Ctrl-Space on some terminals).
Otherwise, the timeout could cause ELinks to resume reading from
the terminal device while another process is still using it.
This actually happened in a test.
On entry to some functions that could resume reading from the device,
assert that the terminal has not been blocked.
To reproduce the bug before this patch:
Enable CONFIG_UTF_8, UTF-8 I/O, and UTF-8 charset.
Go to www.google.com and type "abc" in the text input field.
Then press Left. The cursor jumps to "a" when it should go to "c".
to encode it using utf_8_to_unicode. If every unicode_val_T value
could be a result of that function then one must add out param
to the utf_8_to_unicode signaling 'true' UCS_NO_CHAR.
GPM is awful, tho', and this is an ugly hack. Why can't it just report
buttons like everyone else?
Another nice thing is that we don't seem to get the wheel events more
frequently than once in a second or so. Therefore it will work properly
only when you scroll slooooowly. :^)
When the user presses enter during a text type-ahead search, simply cancel
the search without additionally following the current link. Link type-ahead
searching still will follow the active link on enter.
