We want these behaviors:
- Checking out an obsoleted revision makes it visible even if another
revision was checked out later
- Putting a bookmark on an obsoleted revision makes it visible even if the
bookmark was removed later
- Strip/prune could make them hidden again
This is basically a lightweight version of independent hidden.

Note: Repositories populated by `hg debugbuilddag` don't seem to
|
|
correctly show all commits in the log output. Manually creating the
|
|
commits results in the expected behavior, so commits are manually
|
|
created in the test cases below.

Test recursive restacking -- more complex case. This test is designed to

|
|
stack is lost upon rebasing lower levels.
