Title:
  Broken short options with optional argument (argp parser from libc6
  package)

Status in “eglibc” package in Ubuntu:
  Confirmed

Bug description:
  When GNU option with optional argument is specified in short form and argument is separated from option key by space (e.g., "-F /tmp/blah"), then argument is not seen by argp parser and assumed not specified. But without separating space all OK.
  For options with mandatory argument (for which flag OPTION_ARG_OPTIONAL was not specified in code) this bug doesn't appear: even with space between key and argument the last is seen by parser).

  Applications, using argp.
  Yoshimi 1.0, zynaddsubfx fork, is that place, where i located this bug (first i treated it as yoshimi bug).
  I don't know, what are other applications use argp. Only sure, that apps, using glib or probably, qt4 and other alternative generic libraries, most like to not use argp directly.

  Versions.
  libc6 2.15-0ubuntu10.4 (amd64 binary) from proposed archive
  https://launchpad.net/ubuntu/+source/eglibc/2.15-0ubuntu10.4/
  linux 3.2.0-40-lowlatency from kxstudio
  distro version is 12.04.1
  Note: though it is not ubuntu itself - it is kxstudio, however it supplies only specific packages - just like ubuntustudio).
