5b3c642195 Pass paste buffer through vis(3) when pasting to prevent buffers 
containing for example the bracket end sequence causing issues. -S flag
disables. Reported by Mason Davis.

codepoints (overriding tmux's default list).

aa1353947e UTF-8 keys now contain the internal representation and not the Unicode 
codepoint, so convert extended keys properly. From Stanislav Kljuhhin.

692ce59bce Do not escape $ unless DQ is set, that is the only case where we need to 
escape it.

f09cde2542 Change UTF-8 combining to inspect the previous character at the cursor 
position rather than keeping the last character from the input stream,
this is how most terminals work and fixes problems with displaying these
characters in vim. GitHub issue 3600.

9456258ccc Rewrite combined character handling to be more consistent and to support 
newer Unicode combined characters (which we have to "know" are combined
since they are not width zero). GitHub issue 3600.

77b1290698 More accurate vi(1) word navigation in copy mode and on the status line. 
This changes the meaning of the word-separators option - setting it to
the empty string is equivalent to the previous behavior. From Will Noble

c60389acbf It is not sensible to store pointers into an array we are going to 
realloc (duh), use two trees instead.

a4a3d89598 Use bitshifts instead of a union for encoding UTF-8 into 32 bits, which 
is more friendly to GCC3.

3a5219c6d0 Instead of storing all UTF-8 characters in the extended cell which means 
that 14 bytes are wasted for each character in the BMP, only store
characters of three bytes or less in the cell itself and store others
(outside the BMP or with combining characters) in a separate global
tree. Can reduce grid memory use for heavy Unicode users by around 30%.

979313832c Extend the #[] style syntax and use that together with previous format 
changes to allow the status line to be entirely configured with a single
option.

Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.

Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.

The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

8149bc3fa6 Be more strict about escape sequences that rename windows or set titles: 
ignore any that not valid UTF-8 outright, and for good measure pass the
result through our UTF-8-aware vis(3).

7abdfbe20e OpenBSD wcwidth() is sensible and complete so if it returns -1 it means 
that a character is not printable, so return to ignoring such
characters.

23fdbc9ea6 Loads of platforms appear to have old or broken Unicode character type 
information and are missing widths for relatively common Unicode
characters (so mbtowc() works, but wcwidth() fails). So if wcwidth()
returns -1, assume a width of 1 instead of ignoring the character.

b8a102d26f Handle wcwidth() and mbtowc() failures in better style and drop 
characters where we can't find the width (wcwidth() fails) on input, the
same as we drop invalid UTF-8. Suggested by schwarze@.
