Thank You all for the lively discussion, and of course, a nice and
simple answer to my problem:

At least the haskell.org standard library reference does not say this
(http://haskell.org/ghc/docs/latest/html/libraries/process/System-Process.html), but the information can be found on the System.IO reference page.
As a general comment to this feature, I find it quite acceptable, as on
non-Windows systems it does no harm, and on Windows, you get the desired
behaviour. Seems to reflect closely the practice and distinction in C
