Re: [PATCH v2 2/8] gitweb: Pass esc_html_hl_regions() options to esc_html()

> With this change, esc_html_hl_regions() accepts options and passes them
> down to esc_html().  This may be needed if a caller wants to pass
> -nbsp=>1 to esc_html().
> 
> The idea and implementation example of this change was described in
> 337da8d2 (gitweb: Introduce esc_html_match_hl and esc_html_hl_regions,
> 2012-02-27).  While other suggestions may be more useful in some cases,
> there is no need to implement them at the moment.  The
> esc_html_hl_regions() interface may be changed later if it's needed.
