changeset 15301:0306792cc843

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
lib-storage: Don't crash when searching multiple keywords. Fixed by simply removing the keyword merging code. mail_search_args_simplify() is called before mail_search_args_init(), so the keywords are still NULL and merging can't be done. Alternative fix would have been to add string array to mail_search_arg.value containing the keywords, but all of this is a pretty unnecessary optimization.
