Re: [PATCH] gitweb: fix esc_param

> The custom CGI escaping done in esc_param failed to escape UTF-8
> properly. Fix by using CGI::escape on each sequence of matched
> characters instead of sprintf()ing a custom escaping for each byte.
>
> Additionally, the space -> + escape was being escaped due to greedy

> Finally, remove an unnecessary escaping of the + sign.
