qemu-img: print short help on getopt failure
Printing the full help output obscures the error message for an invalid command-line option or missing argument. Before this patch: $ ./qemu-img --foo ...pages of output... After this patch: $ ./qemu-img --foo qemu-img: unrecognized option '--foo' Try 'qemu-img --help' for more information This patch adds the getopt ':' character so that it can distinguish between missing arguments and unrecognized options. This helps provide more detailed error messages.
