ah, right. so next time I should add a test to demonstrate and verify
the external effect? admittedly part of the reason I hadn't showed
any example output was because I changed this from an internal
perspective. I'll definitely do that next time though. thanks for
the example! (btw, what is the numerical naming convention for
tests?)
you know if no one really liked it as an output we could keep this
change for internal consistency's sake, and filter our added/removed
dirs in the outputing, or even diff_addremove. seems a bit hackish
though...
(also, do you want me to resubmit? because you seem to have taken care of it)
