When sys.executable is long, it may exceed the kernel limits for shebangs, which results in OSError: [Errno 8] Exec format error: 'foo' when launching a tool injected into `PATH.

This is fixed by symlinking the Python interpreter to a short path and emitting that into the shebang.

Looks like this might also fix #24.
