If we are talking about making irreversible change to an existing
repository, we may need to grab one extensions bit (cf.
Documentation/technical/repository-version.txt and then refer also
to Documentation/config/extensions.txt [*]) and flip it when we
wrote a relative link to refer to an worktree and repository.

[Footnote]

 * The repository-version document claims that any extensions
   invented must be registered there, but config/extensions.txt that
   came later ignored it and seems to have acquired a few more than
   the "master list".  We should clean up the mess.
