I'm not sure I understand the question.  I consider the behavior in 
System.IO to be well-documented.  The behavior in System.Process is not 
documented at all.  As I said, I'm not certain what the proper answer 
is, but not documenting what happens probably isn't it.

Actually, the behavior of openFile when given a String with characters > 
0xFF is also completely undocumented.  I am not sure what it does with 
that.  It should probably be the same as runCommand, whatever it is.
