	GNU tar 1.11.2

>Description:
	The '-I' option of tar is used to specify a file containing a list
	of files to create/extract.  Whilst the option parsing code expects
	'-I' to take an option, the string passed to getoldopts() specifies
	that '-I' doesn't take an option.  This leads to NULL being passed
	to strcmp().

>How-To-Repeat:
	echo "/bin" >/tmp/foo
	tar -cf /dev/null -I /tmp/foo

>Fix:
