 Issue3841: check annotation of the file of which filelog includes
 merging between the revision and its ancestor
 
 to reproduce the situation with recent Mercurial, this script uses (1)
 "hg debugsetparents" to merge without ancestor check by "hg merge",
 and (2) the extension to allow filelog merging between the revision
 and its ancestor by overriding "repo._filecommit".
