[PATCH] gitweb: Use descriptive names in esc_html_hl_regions()

The $s->[0] and $s->[1] variables look a bit cryptic.  Let's rename them
to $beg and $end so that it's clear what they do.

P.S. I wonder if it wouldn't be better if we created and used loop-local
variables with descriptive names, e.g.

  my ($beg, $end) = @$s;

and use $beg in place of $s->[0] and $end in place of $s->[1], which are
a bit cryptic.

This of course doesn't affect this patch.

Something like this? (patch not based on this series, may be applied
independently).
