hgweb: handle a "linerange" request parameter in filelog command We now handle a "linerange" URL query parameter to filter filelog using a logic similar to followlines() revset. The URL syntax is: log/<rev>/<file>?linerange=<fromline>:<toline> As a result, filelog entries only consists of revision changing specified line range. The linerange information is propagated to "more"/"less" navigation links but not to numeric navigation links as this would apparently require a dedicated "revnav" class. Only update the "paper" template in this patch.
