gitweb: esc_html_hl_regions(): Don't create empty <span> elements
If $end is equal to or less than $begin, esc_html_hl_regions()
generates an empty <span> element. It normally shouldn't be visible in
the web browser, but it doesn't look good when looking at page source.
It also minimally increases generated page size for no special reason.
