Fix ecpg -? option on Windows, add -V alias for --version.
This makes the -? and -V options work consistently with other binaries.--help and --version are now only recognized as the first option, i.e."ecpg --foobar --help" no longer prints the help, but that's consistentwith most of our other binaries, too.Backpatch to all supported versions.Haribabu KommiDiscussion: <CAJrrPGfnRXvmCzxq6Dy=stAWebfNHxiL+Y_z7uqksZUCkW_waQ@mail.gmail.com>
