[IronPython] Bug when calling ironpythonconsole from powershell

[Neville Bagnall]

In PowerShell drive names are far less restrictive:

PS C:\IronPython> Get-PSDrive

Name       Provider      Root
----       --------      ----
Alias      Alias
C          FileSystem    C:\
cert       Certificate   \
D          FileSystem    D:\
E          FileSystem    E:\
Env        Environment
Function   Function
HKCU       Registry      HKEY_CURRENT_USER
HKLM       Registry      HKEY_LOCAL_MACHINE
Variable   Variable

So when the parser sees -X:SaveAssemblies it thinks it is the  
"SaveAssemblies" item on the "-X" Drive.

If you enclose the item in quotes '-X:SaveAssemblies' the parser will  
interpret it as a string and pass it through.

PS C:\IronPython> .\IronPythonConsole.exe '-X:SaveAssemblies'

"Interestingly", cmdlets do the right thing:

PS C:\IronPython> gci -r:0

PS C:\IronPython>

Probably because the parser gets the parameter information through  
reflection.
