It is saying _all_ these have to be true, and we already quote
executables, and the string, so we always have more than two quotes:
* Win32 needs double quotes at the beginning and end of system()* strings. If not, it gets confused with multiple
quotedstrings.* It also requires double-quotes around the executable name and* any files used for redirection. Other
argscan use single-quotes.
