start_batch_changes() doesn't avoid invoking the clipboard
once-per-line, because the loop is actually in ex_echo(), which calls
redir_write() for each message. But we've already entered
start_batch_changes() by then, so that was never the problem.

Trying to defer _explicit_ clipboard updates is difficult.
:redir @+ | silent echo system('cat foo') | redir END
is essentially equivalent to:
for l in readfile('foo')
let @+ .= l
endfor
We cannot make judgements about when to ignore a script's bad decisions.
start_batch_changes() only works around the case of clipboard=unnamed,
i.e. _implicit_ clipboard updates (`:g/foo/d`). Not explicit
assignment.
redir_write():
- This is a "batch" operation which was not yet covered by
start_batch_changes()
adjust_clipboard_name():
- msg() and friends during :redir will, of course, cause redir_write()
to try to capture that message, which causes recursion.
- EMSG() here is trouble: if it interrupts :redir it is a mess.
Rather than deal with the mess, show a non-error message.

Group some options, and sort them alphabetically.
`nvim -h` should fit on one (smallish) screen.
Uncommon options don't need to be here, they live in the :help.

Problem: When 'equalalways' is set and closing a window in a separate
frame, not all window sizes are adjusted. (Glacambre)
Solution: Resize all windows if the new current window is not in the same
frame as the closed window. (closesvim/vim#1707)

To deal with SIGWINCH limitations on Windows, change some resize tests
to _shrink_ the screen width. ... But this didn't work, so still
ignoring those tests on Windows.
- Make sure that proc->in is not NULL, because nvim crashed when
starting a job with pty.
- Make sure that proc->out is not NULL, because nvim crashed when stopping
a job opened with pty.
Handling of process exit is still broken. It detects the moment when the
child process exits, then quickly stops polling for process output. It
should continue polling for output until the agent has scraped all of the
process' output. This problem is easy to notice by running a command like
"dir && exit", but even typing "exit<ENTER>" can manifest the problem --
the "t" might not appear.
winpty's Cygwin adapter handles shutdown by waiting for the agent to close
the CONOUT pipe, which it does after it has scraped the child's last
output. AFAIK, neovim doesn't do anything interesting when winpty closes
the CONOUT pipe.
