It doesn't follow the ambiguous file name searching for CreateProcess.
I just re-read the cmd.exe help output and realized that it spells out
the logic for quotes when /c is specified. My patch was overarching in
also affecting commands entered at the command prompt; it should only
affect the command line passed in as an argument with the /c flag.
