Why?  The option order doesn't usually matter for separate standalone
options, and if the order does matter, the function isn't going to be
able to guess which way round things have to be anyway.  I quite
deliberately did it the way I did because of options taking arguments.
Consider (example contrived on the spur of the moment, but not wholly
unrealistic):

  su -c 'rm -f .zshrc' username -l

Your way, this becomes

  su -c -l 'rm -f .zshrc' username

which is wrong.
