Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revlog: rename 'self.checkinlinesize' into '_enforceinlinesize' The name change has two motivations: 1) The function has no external caller, so we move it to protected space. 2) the function does more than checking it also split the data if we have more data than 'inline' supports.
