Confirmed.

Yes, that would be nice.

The problem is as follows. The function help() catches the special funs
like "+" etc (more precisely, the arithmetic, comparison, logic and
extract ones) and directly assigns a topic for them.
For "+", the topic is 'Arithmetic". But the index file has no entry for
that, because (see RHOME/etc/install-help)
***********************************************************************
if [ $lib != 'base' ]
##-- The following is NOT done anymore in 'base':
##-- 1) Each help file should have ALIAS(..) for ALL it's objects
##-- 2) The help file name may differ from _ANY_ object (eg 'Special')
then
for file in $FILES
do
echo "$file $file"
done
fi
***********************************************************************
If that really is the intended usage (Martin?), then e.g. the Arithmetic
file should also have ALIAS(Arithmetic) in it.
