revlog-split: show manifest data loss situation when using clonebundle
After the commit of the transaction from applying the clone bundle, changes to
the manifest from the subsequent pull would write index data in the wrong file.
This lead to data being "lost" after the pull and the repository to be
corrupted. We add a test checking this specific scenario.
In practice, the issue only affects the manifest but we also test the issue with a file for future proofing things up.
See test documentation and failure for details.

Testing recorded "modified" files for merge commit ================================================== #require execbit This file shows what hg says are "modified" files for a merge commit (hg log -T {files}), somewhat exhaustively.
