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").
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.

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.

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.
