Problem: The return value of mode() does not indicate that completion is
active in Replace and Insert mode. (Zhen-Huan (Kenny) Hu)
Solution: Add "c" or "x" for two kinds of completion. (Yegappan Lakshmanan,
closes#1397) Test some more modes.
Problem: When calling setpos() with a buffer argument it often is ignored.
(Matthew Malcomson)
Solution: Make the buffer argument work for all marks local to a buffer.
(neovim #5713) Add more tests.
Problem: It is not so easy to write a script that works with both Python 2
and Python 3, even when the Python code works with both.
Solution: Add 'pyxversion', :pyx, etc. (Marc Weber, Ken Takata)
Problem: To pass buffer content to system() and systemlist() one has to
first create a string or list.
Solution: Allow passing a buffer number. (LemonBoy, closes#1240)
Problem: When using ch_read() with zero timeout, can't tell the difference
between reading an empty line and nothing available.
Solution: Add ch_canread().
Problem: When the input or output is not a tty Vim appears to hang.
Solution: Add the --ttyfail argument. Also add the "ttyin" and "ttyout"
features to be able to check in Vim script.
Problem: Cannot get the number of the current quickfix or location list.
Solution: Use the current list if "nr" in "what" is zero. (Yegappan
Lakshmanan) Remove debug command from test.
Problem: Can't tell which part of a channel has "buffered" status.
Solution: Add an optional argument to ch_status(). Let ch_info() also
return "buffered" for out_status and err_status.
Problem: getwininfo() and getbufinfo() are inefficient.
Solution: Do not make a copy of all window/buffer-local options. Make it
possible to get them with gettabwinvar() or getbufvar().
Problem: The field names used by getbufinfo(), gettabinfo() and
getwininfo() are not consistent.
Solution: Use bufnr, winnr and tabnr. (Yegappan Lakshmanan)
Problem: It's not easy to find out if a window is a quickfix or location
list window.
Solution: Add "loclist" and "quickfix" entries to the dict returnec by
getwininfo(). (Yegappan Lakshmanan)
Problem: It is not easy to get information about buffers, windows and
tabpages.
Solution: Add getbufinfo(), getwininfo() and gettabinfo(). (Yegappan
Lakshmanan)
Problem: Using function() with a name will find another function when it is
redefined.
Solution: Add funcref(). Refer to lambda using a partial. Fix several
reference counting issues.
Problem: User defined functions can't be a closure.
Solution: Add the "closure" argument. Allow using :unlet on a bound
variable. (Yasuhiro Matsumoto, Ken Takata)
