distant_name() temporarily blinded the hero before calling xname() or
doname() in order to prevent the object being formatted from having
its dknown flag set. The Eyes of the Overworld override blindness, so
that bit got set for heros wearing them regardless of intention. This
switches to a file-scope global instead of blindness as the way that
distant_name() tells xname() not to set dknown.
This bug has been present ever since the Eyes were added (3.3.0?).
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.
