Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
context: preserve changeset in filectx if we have one If we know original changeset we are working with - try hard to preserve it. Fallback to filelog.linkrev() only if we have no way to get original changeset, since linkrev() may point to other changeset.
