I've tried this from the msys-shell, for example g.region, r.blend, ..., and if I remember correctly, this worked by popping up the gui until a week ago or so. 

here is the error message:

"GRASS 6.4> r.blend

Fehler: Benötigter Parameter <first> ist nicht gesetzt:
    (Name der ersten Rasterkarte für die Mischung.).

error: needed parameter <first> not set

Fehler: Benötigter Parameter <second> ist nicht gesetzt:
    (Name der zweiten Rasterkarte für die Mischung.).

error: needed parameter <second> not set

Fehler: Benötigter Parameter <output> ist nicht gesetzt:
    (Präfix für die rote, grüne und blaue Ausgabekarte der erstellten Mischung.).

error: needed parameter <output> not set"


but it's working from the wx-gui-command-line, from the tcltk-command-line (by the buttons "run in background","run GUI", and "run in DOS-box").

tested here on another WinVista32-box withthe nightly build WinGRASS-6.4.SVN-r40792-1-Setup.exe
