[Bug libc/2714] New: Contradiction in the implementation of optional arguments in getopt()

["alpt at freaknet dot org" <sourceware-bugzilla at sourceware dot org>]

Hi there,

this is the problem: 

        foo -abcRdefg

If 'R' is an element that specifies an optional argument, then the "defg"
string is taken as its argument, it is pointed by optarg,
but this is not what the user wants, in fact, he expects that the "defg"
characters are parsed as other option elements. In other words the user
expects this:
        
        foo -abc -R -defg

The solution is to assign arguments to 'R' only in these cases:

        foo -abcR option_to_R
        bar -abc -R option_to_R

The patch is here:
