Move the 'if (wizard) { /* give feedback for named fruit */ }' code
in ^X/enlightenment into an #if DEBUG block, and expand the if (wizard)
predicate with '&& explicitdebug("fruit")' to require that 'fruit' be in
DEBUGFILES. So, build with DEBUG enabled and run via
|% DEBUGFILES='fruit' nethack
to get it back....
This isn't actually a bug fix and it isn't necessary for 3.6.1, but I
got tired of seeing ^X and end-of-game disclosure of attributes end with
three lines about fruit when I'm not doing anything with named fruit.
