No, this won't work because it only looks for the command to match if it is 
immediately followed by a space, tab, or newline.  So, for example, "echo.blah" 
doesn't match "echo."  This is a unique cmd.exe command that doesn't require 
whitespace between the command and the first argument as long as echo is 
immediately followed by a '.'.
