            Bug ID: 42964
           Summary: Allow "-<integer>" as an alias for "-n integer"
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: llvm-strings
          Assignee: unassignedbugs at nondot.org

llvm-strings doesn't allow "-1", "-2" etc as aliases for "-n 1", "-n 2" etc,
unlike GNU strings. We should add those aliases.

Once this is fixed, we should show that cases like "-n -1" produce sensible
behaviour. In this case, it should probably be rejected as -1 isn't a valid
argument for -n, or because -n is missing an argument.
