Bug fix and zsh-async 1.8.0
Bug fix. On ZSH v5.0.0-2, a function of the type
foo() {
setopt LOCAL_OPTIONS WARN_CREATE_GLOBAL
FOO=bar ls
}
triggers the warning
foo:2: scalar parameter FOO created globally in function
This fix prevents that sort of warning from being displayed for _agkozak_precmd.
Also, version 1.8.0 of zsh-async is now used.
