This commit allows pgit.sh to target not only multiple projects below a projects-directory, but also one single project. If invoked from the toplevel directory of a project, it uses that as the only project it should deal with. This is meant to facilitate running the same VCS abstraction logic for one project as for many projects. The project or projects to deal with should probably be specified on the command line, but changing the auto-detection mechanism buys us what we want for now with low hassle.
