+   - '*', '?' 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.
