I'm not a user of add -i and didn't review the main logic in detail,
but I ran this, and aside from two issues this LGTM:
* You missed a trailing \n in the output, so your formatting is
different from the current behavior.
* You should be using the getopt API instead of rolling your own.
Fixes for both below, thanks a lot for hacking on this. As you pointed
out this doesn't help with removing any of the perl code for now, but
after replacing a few more command modes we can start chopping away at
the perl code.
