Your conversion is fine, but this does highlight that the code here
interprets *everything* except "off" as "on" (including "OFF", "no",
"Off", "0").

There are actually many similar instances in the parser code. Should we
continue to be so silently strict? Or complain any time the string isn't
*exactly* "on" or "off"? Or make it extremely tolerant about what is
entered (0, off, Off, no, false all mean the same thing)?

Is it worth making a helper function that takes a const char * and
returns true/false according to whatever rules we decide, then use that
everywhere there is an on/off (or yes/no) attribute?
