No. You misunderstand. I was mainly concerned with the `/dev/null`. Every
Windows developer knows what `>file.txt` means, and many know what
`2>error.txt` means. But `/dev/null` is not Windows, period. It is so not
Windows that Git itself translates it to `NUL` (which you Linux die-hards
won't have a clue about, I would wager a bet).

No. The value is a path. I can special-case values that are not even valid
Windows file names (such as `2>&1`). I cannot special-case values that are
perfectly valid paths.

True. Fixed. I also threw in an example for a pipe.
Ciao,
