-   Instead it simply concatenates the arguments, separated by ' ', and calls
-   CreateProcess().  We must quote the arguments since Windows CreateProcess()
-   interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a
-   special way:
-   - Space and tab are interpreted as delimiters. They are not treated as
-     delimiters if they are surrounded by double quotes: "...".
-   - Unescaped double quotes are removed from the input. Their only effect is
-     that within double quotes, space and tab are treated like normal
-     characters.
-   - Backslashes not followed by double quotes are not special.
-   - But 2*n+1 backslashes followed by a double quote become
-     n backslashes followed by a double quote (n >= 0):
-       \" -> "
-       \\\" -> \"
-       \\\\\" -> \\"
-   - '*', '?' characters may get expanded through wildcard expansion in the
-     callee: By default, in the callee, the initialization code before main()
-     takes the result of GetCommandLine(), wildcard-expands it, and passes it
-     to main(). The exceptions to this rule are:
-       - programs that inspect GetCommandLine() and ignore argv,
-       - mingw programs that have a global variable 'int _CRT_glob = 0;',
-       - Cygwin programs, when invoked from a Cygwin program.
