Just a minor point - why export on a separate line instead of export VIRTUAL_ENV=$(cygpath "__VENV_DIR__") as it was before?

Declaring and assigning a variable at the same time can mask the return value if the command fails. Doing them separately won't which can help with debugging and error handling.
