annotate plotss.py @ 79:84f96c5fe791

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use different message ID that does not result in "Query UNTERMINATE" messages in the error log. Fix testsrq. Rename queryrsb to querystb as that matches the operating manual.
