New description:

 {{{
 When given RequireOrder the getOpt' function should not
 parse options
 following a non-option.  But currently (as of version
 6.4.1 of ghc) it
 does.  E.g. when parsing with RequireOrder and if
 invalid-opt3 is not a
 recognized option then the following produces an error:

   progname --valid-opt1 --valid-opt2 non-opt --invalid-opt3

 However, anything after non-opt should not be parsed.
 The problem can be
 fixed as follows:

 164c164
 <          procNextOpt (NonOpt x)   RequireOrder      =
 ([],x:rest,us,[])
 ---
 >          procNextOpt (NonOpt x)   RequireOrder      =
 ([],x:rest,[],[])

Comment:

 The bug has already been fixed in the 6.4.2 branch, and it is now fixed in
 the HEAD, too.
