Details:

This came up in bug #60639.

I don't think lines 112-113 of src/utils/addftinfo/addftinfo.cpp work as
intended.


    $ addftinfo -asc-height -body-depth 60
    usage: addftinfo [-v] [-param value] ... resolution unitwidth font
    $ addftinfo -body-depth 60 -asc-depth
    usage: addftinfo [-v] [-param value] ... resolution unitwidth font


The code should be emitting a complaint diagnostic before (or instead of) the
usage message, but this doesn't happen.

Setting severity to "minor", both because the user can infer that they screwed
up and because probably few people have any reason to use this utility these
days.
