hgweb: teach archive how to download a specific directory or file The archive web command now takes into account the "file" request entry, if one is provided. The provided "file" is processed as a "path" corresponding to a directory or file that will be downloaded. With this change hgweb can to process requests such as: http://mercurial.selenic.com/hg/archive/tip.zip/mercurial/templates This will download all files on the mercurial/templates directory as a zip file. It is not possible to specify file patterns ('glob', 'relglob', 'path', 'relpath', 're', 'relre' nor 'set'). The server will reject those with a 403 HTTP error response. Note that this is a first step to add support for downloading directories from the web interface. A following patch will modify the archiveentry map entry on the different templates so that it adds the current folder path to the archive links.
