When people find bugs in scripts such as reindent.py, msgfmt.py or pygettext.py, we have to try to reproduce the bug manually, apply a fix and test manually again. The alternative is to only read the code and trust that it works. This test file is a way to stop that unsatisfactory state of things and write proper unit tests instead.
