[R-SIG-Mac] [R] txtStart creates a NULL file

[R. Michael Weylandt]

Like others in the referenced thread, I can reproduce this on Mac OS X
10.5.8 with R 2.14.1 using R.app but it works just fine from the
Terminal CLI so it's likely something in the GUI rather than R itself:
I'll forward this to R-SIG-Mac and see if Simon (Urbanek) picks it up.
