annotate rlgwebd @ 213:08665c56c6a0 default tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix race condition related to watching DGL games. It's possible for a dgamelaunch game to end and cause rlgwebd to stop watching it before rlgwebd has started watching it.
