• Send a patch file-name in the HTTP header via the Content-Disposition header.
• When downloading/referring to a particular patch embed the patch number with the PR instead of using two different CGI variables. This means that there aren't "&" in the patch URL's anymore which makes things simpler for sh(1) like shells, by not requiring quoting of URLs when using a command line tool, such as fetch(1), to download patches.
• In HTML-ifying of URL's, handle when a URL contains a PR like string which can e.g. be seen in PR www/113071.
• Add a comment about how to test script via the command line.
