The last condition in cmd.exe manpage states:
"""
- the string between the two quote characters is the name of an 
executable file.
"""

I am not sure what they mean by that. I do not think there is anything 
like an executable bit in NTFS or even FAT, but %PATHEXT% filters 
"command" files:

<http://www.microsoft.com/technet/archive/winntas/deploy/shellscr.mspx?mfr=true>
"""
The PATHEXT environment variable defines the list of file extensions 
checked by Windows NT when searching for an executable file. Like the 
PATH variable, semi-colons separate individual items in the PATHEXT 
variable. The default value of PATHEXT is .COM;.EXE;.BAT;.CMD.
"""

Conditions I am trying to detect could be found there:
