transaction: tests we don't overwrite branch changes on abort

We actually do not! Great.

…Why are doing a backup of the `branch` files at transaction creation then‽

(this file is backported from core hg tests/test-annotate.t)

(note on question marks:

 +38ed54888617) alters the output so deletion is not always at the end of the

(rev 1 adds two "a"s and rev 6 deletes one "a".
 the "a" that rev 6 deletes could be either the first or the second "a" of those two "a"s added by rev 1.
 and that causes the line number difference)

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".
