hgweb: fixed invalid atom-log feed url in file log page
currently "subscribe to atom feed" link in file log page is as follows.
/atom-log/[revision]/[file]
This is invalid, because we could not get newer commit feed than [revision].
To fix this, atom-log feed url should be the following style.
atom-log/tip/[file]
