68343c8de4 Allow suggestions to suggest trailing newlines
Command substitution via $() trims trailing newlines so the old approach
to reading everything from the fd was preventing suggestions from ending
with newlines.

d94475ca1b Simplify logic to extract suggestion from between null bytes
Just remove up to and including the first null byte and after and
including the last null byte.

I also looked into using `${${(0)line}[2]}`, but it fails when `$line`
starts with a null byte, since the first split string will be empty and
thus not included in the resulting array.

0d3bbaf8e6 Remove hard-coded ignore of zle-* widgets and add to default config
Use case suggested by @romkatv uses zle-line-init to restore buffer
after running a widget to cd up one level (GitHub #431).

As far as I can tell, the ignoring of zle-line-* was added in commit
9788c2e to support some deprecation warnings that were removed some time
ago.

The pattern was then widened in commit 0c940e7 to zle-* to fix problems
encountered when wrapping zle-isearch-update.

This commit removes the hard coded ignore of all zle-* widgets and adds
zle-* to the default list of widgets to be ignored. Users who want the
plugin to wrap zle-line-init or zle-line-finish can override the
default.

15bcfd7126 Don't fetch suggestions after copy-earlier-word
Like {up,down}-line-or-beginning-search, this widget relies on
`$LASTWIDGET` being set to function correctly on subsequent invocations.

When asynchronous suggestions are enabled, and the widget triggers a
suggestion to be fetched, `autosuggest-suggest` will be called and
$LASTWIDGET will be set to it.

474c577f3c Allow setting max size to empty string (GitHub #422)
Some people have gotten used to setting ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE
to an empty string rather than leaving it unset. This lets them continue
to do that without getting any warnings (e.g. "bad math expression:
operand expected at end of string").

c1910348c7 Implement completion suggestion strategy (#111)
Based on https://github.com/Valodim/zsh-capture-completion

`zpty -r` with a pattern seems to have some funky behavior on older
versions, giving unpredictable results

Don't use `-s` option to `zmodload`. It is not available in zsh versions
older than 5.3

If running in sync mode and a completion takes a long time, the user can
^C out of it. We need to use `always` in the strategy function or the
pty will not be destroyed in this case and the next time we go to create
it, it will fail, making the shell unusable.

User can have many different completion styles set that will modify what
they've already typed. These styles will result in suggestions that
don't match what the user has already typed. We try our best to unset
some of the more problematic ones, but add some code to fetch to
invalidate suggestions that don't match what the user's already typed.

e405afab29 Refactor async mode to no longer use zpty
See technique used in `fast-syntax-highlighting`:
- ca2e18bbc9
- http://www.zsh.org/mla/users/2018/msg00424.html

Also see http://www.zsh.org/mla/users/2018/msg00432.html

In async response handler:
- We only want to read data in case of POLLIN or POLLHUP. Not POLLNVAL
  or select error.
- We always want to remove the handler, so it doesn't get called in an
  infinite loop when error is nval or err.

There is an upstream bug that prevents ctrl-c from resetting the prompt
immediately after a suggestion has been fetched asynchronously. A patch
has been submitted, but a workaround for now is to add `command true`
after the exec.

f1c3b98774 Only capture completions at the end of the buffer.
To prevent the suggestion from not starting with the buffer string.

Example:

`ls / /[cursor left][cursor left]b`

Before the patch, suggests `ls /b /ls /bin/ /`

After the patch, suggests `ls /b /bin/`.
