qnew: omit meaningless and harmful putting subrepositories into target list Before this patch, qnew puts updated subrepositories into target list forcibly, if any of -I, -X or patterns are specified. But this is meaningless and harmful, because: - putting subrepositories into target list doesn't affect the result of "localrepository.status()" "dirstate.status()" invoked via "localrepository.status()" always omits subrepositories from the result of it - any -I/-X opts and empty "pats" causes unexpected failure when any -I/-X opts are specified, "inclsubs" are always added to "pats", even if "pats" is empty. but this changes meaning of "pats" from "including all to be included" to "including only listed subrepositories" this may exclude ".hgsub" and cause unexpected exception raising ("can't commit subrepos without .hgsub" ). - qnew at other than repository root (with -I, -X or any patterns) causes unexpected failure "scmutil.match()" treats pattern without syntax type as 'relpath' type (= one rooted at cwd). but qnew puts subrepository paths rooted at the repository root, and it causes unexpected exception raising ("SUBREPO not under root ROOT" in "pathutil.canonpath()"), if "hg qnew" is executed at other than repository root with -I, -X or any patterns. This patch omits meaningless and harmful putting subrepositories into target list. This omitting doesn't miss including updated subrepositories, because subrepositories are specified to "scmutil.matchfiles()" directly, to get "match" object for "localrepository.commit()".
