tests: make merge conflicts explicit in `hg annotate` tests

We were using `true` as merge tool. I think it makes the test easier
to understand if we make the conflicts explcit. It also papered over a
conflict that shouldn't have been a conflict (just a bug in copy
tracing). I've marked that "BROKEN".

 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".

  the "a" that rev 6 deletes could be either the first or the second "a" of those two "a"s added by rev 1.

 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".
