computing syntax highlighting for the command-line buffer as it stands at the
time z-sy-h's hook is invoked.
In zsh 5.2 and older,
`zsh-syntax-highlighting.zsh` hooks into ZLE by wrapping ZLE widgets. It must be sourced after all
custom widgets have been created (i.e., after all `zle -N` calls and after
running `compinit`). Widgets created later will work, but will not update the
running `compinit`) in order to be able to wrap all of them.
Widgets created after z-sy-h is sourced will work, but will not update the
syntax highlighting.
In zsh 5.3 and newer,
zsh-syntax-highlighting uses the `add-zle-hook-widget` facility to install
a `zle-line-pre-redraw` hook. Hooks are run in order of registration,
therefore, z-sy-h must be sourced (and register its hook) after anything else

### Does syntax highlighting work during incremental history search?
