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.
