I also believe these were the original semantics, but they are difficult to get around in a modern environment. Also of course this assumes that the user is even using xterm. Perhaps there should be something like
SNOTES_TERMINAL="xterm -e" And, if SNOTES_TERMINAL is defined, it is put under wordsplitting and used (no arrays if we want to be POSIXly correct).
