The ':tcd' command is the first tab-specific command written to the file
and it is wrapped inside an 'if has('nvim')' block to keep the session
file compatible with Vim.
Closes#6678
In order to generate INT64_MIN from literal values, it's necessary to
use "-0x7fffffffffffffff - 1". Using "-0x8000000000000000" causes the
value to get clamped to INT64_MAX and then negated.
If if the resolved $NVIM_LOG_FILE *and* stdpath("data")/log cannot be
created (e.g. because the XDG data directory does not exist), fall back
to .nvimlog in the current direcrtory.
Reverts commit 337b6179dfCloses#6716 at the expense of not being able to use a
multi-key 'pastetoggle' manually.
Multi-key 'pastetoggle' can still be used when inserting the entire
option into the typebuffer at once (though the use here is
questionable).
Also remove those tests to do with waiting for the completion of
'pastetoggle' and mention in the documentation that 'pastetoggle'
doesn't wait for timeout.
When the end character in a range matches a different standard range
(e.g., [0-z]), the range would be incorrectly detected as the class of
the end character (CLASS_az).
Instead of using a fallthrough, immediately FAIL when the end character
doesn't match the expected range.
The terminfo entry for linux only advertises 8 colours, but nvim tries
to make it display 16 colours anyway, resulting in erroneous SGR control
sequences for colours 8 and above. The Linux kernel terminal emulator
itself has actually understood the 256-colour control sequences since
version 4.8 and the 16-colour control sequences since version 4.9. Thus
we apply the same terminfo fixup as we apply for *xterm* and *256*, to
emit the 16-colour and 256-colour control sequences even if terminfo's
setaf and setab do not advertise them.
As part of the refactoring in #5119, some vim_strchr() were changed to
strchr(). However, vim_strchr() behaves differently than strchr() when
c is NUL, returning NULL instead of a pointer to the NUL.
Revert the strchr() calls where it isn't known whether c is NUL, since
this causes a semantic change the surrounding code doesn't expect. In
the case of #6650, this led to a heap overrun.
Closes#6650
