Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
uncommit: abort when rev specifies the current changeset The uncommit command now fails when the rev argument indicates the current changeset. Previously this aborted in the changeset obsolescence machinery when the current commit tries to obsolete itself. Using the rev argument like this indicates a misunderstanding, so printing an uncommit-specific error should make it easier to understand what went wrong.
