I'm puzzled by the default index_format which is, I think:
set index_format="%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?) %s"I don't understand the string inside parentheses. Where can I find an explanation? Question marks often invoke some sort of conditional action, but I don't see them in printf docs. TIA -- Paul E Condon pecon...@mesanetworks.net
