Add `bracketed-paste` to list of widgets that clear the suggestion as a
workaround for GitHub #351

So that you can access defaults to e.g. add elements to an existing
array.

v0.5.2

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.

Allow disabling of automatic widget re-binding

Addresses github #411

Refactor async mode to no longer use zpty

See technique used in `fast-syntax-highlighting`:

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.

Fixes GitHub #379

They're not quite ready. Keep them on a feature branch for now.

Releases/v0.5.0

otherwise users are obliged to set the config values *after* sourcing
the plugin. They're not able to do it before. Also, re-sourcing the
plugin will reset the values to the defaults again.

Should fix GitHub #334

Fixes #337

`stty` occasionally hangs (always in CircleCI) inside the async pty.

Disable the tests for now until we can figure out and fix/workaround
this issue.
