Bash already has programmable tab completion, although I'm not sure if you would be able to hook argument reordering into it easily. But PLEASE don't assume the entire world is elf. Bash is ported to a number of non-elf platforms, such as PE-COFF of Windows. Hooking in a readline command that examines the command enough to know which options take arguments so that reordering will not change the semantics of the command sounds admirable, but doing so by parsing the target executable just does not sound like the right approach to me. We don't need to bloat bash by adding all of the binutils capabilities into it. - -- Life is short - so eat dessert first!
