Hmm.  So if any one of the selected projects doesn't have a Git
repository at its top level we just plain fail and pretend none of
them have a Git repository?  That doesn't seem right to me.  We
should just skip that project and move to another project.

But I also wonder if that really makes sense when a project could
have a linked resource under it that points to the repository's
working directory.  In such cases we want operations on that project
to potentially impact the inner repository as maybe the project
repository does not have a repository itself.  IOW I'm questioning
the idea of getRepositoriesFor(getProjectsForSelectedResources()).
