debugbuilddag: build a changelog dag from a concise description
Useful in tests to quickly build a complex DAG in an empty repo.
Handles local tags and named branches.
Options to, at each rev,
- create a new file,
- overwrite the same file,
- append to the same file,
- write to a specific line in a mergeable file.
Can run shell commands during DAG buildup.
