emxomfar does not accept '-' before command parameter

[Yuri Dario]

While ar accepts an optional '-' before the command char, emxomfar doesn't because it checks for -p and then aborts.

Proposed patch ignores also letters for valid commands

(In [3701]) emxomfar: Fixed and relaxed the command/option parsing so that they can be given with a dash (was broken) and in more than one argument. Should probably insist on the command comming first, but who cares. References #184.

(In [3702]) 0.6/emxomfar: Backported r3701: Fixed and relaxed the command/option parsing so that they can be given with a dash (was broken) and in more than one argument. Should probably insist on the command comming first, but who cares. Fixes #184.

[Yuri Dario]

As side effect of fix, now if -p is added to command line, commands must start with a '-' otherwise they are not recognized.

it depends on next option code (line#326):

      /* more options? */

      if (i >= argc)
        usage ();
      s = argv[i];
      if (*s != '-')
        break; /* not an option */
