The repo can't be cloned on Windows completely due to a path that is too long.

[Poikilos]

The too-long path test is too long for Windows.

• The bug seems to have been introduced in: b73078a
• The repo doesn't need to have this unusable path:
  • The test can generate the directory.
  • The generated file can be added to gitignore (and/or the test can delete the directory; the file never needs to be created for the test to work).
