Bug#345342: libc6: getopt doesn't support utf-8

[Mikko Tuumanen <mijutu@utu.fi>]

Package: libc6
Version: 2.3.5-9

When using UTF-8 locales, getopt prints the error message in a wrong way, if
a wrong multibyte character was given as an option.

Start an utf-8 terminal:
$ LC_ALL=en_GB.UTF-8 uxterm -fn -Misc-Fixed-Medium-R-Normal--20-200-75-75-C-100-ISO10646-1

Then run ls there:

$ ls -ö
ls: invalid option -- 
                       Try ls --help' for more information.

It prints only the first byte of the multibyte character.
