… Windows

Same as on POSIX-compliant platforms.

* e.g. run 'd.vect map=census where="cat > 10 AND cat < 20"' with
where parameter from Command Prompt CMD/emulator terminal:

non-POSIX platform

```
>>> import shlex
>>> shlex.split('where="cat > 10 AND cat < 20"', posix=False)
['where="cat', '>', '10', 'AND', 'cat', '<', '20"']
```

POSIX-compliant platform

```
>>> import shlex
>>> shlex.split('where="cat > 10 AND cat < 20"', posix=True)
['where=cat > 10 AND cat < 20']
```

Under OS MS Windows 'd.vect map=census where="cat > 10 AND cat < 20"'
command runned from Command Prompt CMD require use ^ carret symbol for
escaping special characters < > ( ) & | , ; ".

e.g. 'd.vect map=census where="cat ^> 10 AND cat ^< 20"'
