test-bundle2: add bookmark movement to the push test

If we add bookmarks to bundle2, we need a way to test the new code.
Tests are changed beforehand to highlight that inclusion of bookmarks in bundle
does not introduce any behavior changes.

Test histedit extension: Fold commands
======================================

This test file is dedicated to testing the fold command in non conflicting
case.

Initialization

Simple folding

folding and creating no new change doesn't break:

folded content is dropped during a merge. The folded commit should properly disappear.
