options: stop recognizing and ignoring -b, -e, -f, -j, and -q

This signals our break from trying to be as compatible with Pico as
possible.  We were already incompatible with modern Pico in the -n
and -W options, and in several character-set and color options, so
ignoring those five options brought us very little.

Anyway, soon some of those options will be reused and will have the
effect of making nano look and behave more like Pico.
