Test case

After a call to g_option_context_set_ignore_unknown_options(context, TRUE),
the values of short options are included in the array returned by a
G_OPTION_REMAINING option. If G_OPTION_REMAINING is not used, the short
options' values are (correctly) removed from argv[].

Some results with the attached test case:

  $ ./testcase --number 4 --text=hello file1 file2
  ignore=0:0, remaining=0:0, number=4, text=hello, files=, argv= ./testcase file1 file2

  $ ./testcase -r --number 4 --text=hello file1 file2
  ignore=0:0, remaining=1:1, number=4, text=hello, files= file1 file2, argv= ./testcase

  $ ./testcase -n 4 -t hello file1 file2
  ignore=0:0, remaining=0:0, number=4, text=hello, files=, argv= ./testcase file1 file2

  $ ./testcase -r -n 4 -t hello file1 file2
  ignore=0:0, remaining=1:1, number=4, text=hello, files= file1 file2, argv= ./testcase

  $ ./testcase -i --number 4 --text=hello file1 file2
  ignore=1:1, remaining=0:0, number=4, text=hello, files=, argv= ./testcase file1 file2

  $ ./testcase -ri --number 4 --text=hello file1 file2
  ignore=1:1, remaining=1:1, number=4, text=hello, files= file1 file2, argv= ./testcase

  $ ./testcase -i -n 4 -t hello file1 file2
  ignore=1:1, remaining=0:0, number=4, text=hello, files=, argv= ./testcase file1 file2

  $ ./testcase -ri -n 4 -t hello file1 file2
  ignore=1:1, remaining=1:1, number=4, text=hello, files= 4 hello file1 file2, argv= ./testcase

The last result is wrong. "4" and "hello" shall not be considered remaining
options.

I will add a patch.
