[Qemu-block] [PATCH v2 0/3] qemu-img: improve qemu-img getopt error messages

[Stefan Hajnoczi]

v2:
 * Print short help to avoid obscuring error messages [Max]

This series improves getopt error messages.  Unrecognized global options were
skipped rather than causing qemu-img to exit as expected.  Also avoid printing
the full help text because it obscures the actual error message.

Stefan Hajnoczi (3):
  qemu-img: show help for invalid global options
  qemu-img: fix switch indentation in img_amend()
  qemu-img: print short help on getopt failure
