* A utility function for test and tools that compensates (at least for very
* simple cases) for file-dependent programs being run from different
* directories. The important cases are
* -running in the directory that contains the test itself, i.e.
* pkg/intl/test or a sub-directory.
* -running in pkg/intl, which is where the editor will run things by default
* -running in the top-level dart directory, where the build tests run
