Not sure, I am just pointing out what is going to change for people by making this switch due to the way getopt_long works.

For LLVM you might need to do this:

% lldb --arch=x86_64 -- /bin/ls -lAF

All args might need to be past all of the options and after the "--". I just don't know and was pointing out the differences people are likely to be confused by.
