changeset 197:3181a6b5758e

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
FIX: Using a pipeline within a function correctly with regard to return values: The last pipeline element determines the status. Account for this. So instead of a here-doc a pipeline can be used.
