I wasn't aware that [^] and [$] work for options too.

In fact you get "something" - [^] and [$] get pre-/appended at the time
the line "Options[ethernet.1]: something" is completly parsed. The
"Options[$]:" only affects the following lines. This is documented!


If you think this is hard to understand remember that it's a grown
parser/configuration language ;-}
