We used to have extensions automatically sorted because they came from a
single glob, that was itself sorted.
fi
set X $known_extensions
shift
-known_extensions="$*"
+known_extensions=`echo "$*" | tr ' ' $trnl | $sort | tr $trnl ' '`
set X $nonxs_extensions
shift
-nonxs_extensions="$*"
+nonxs_extensions=`echo "$*" | tr ' ' $trnl | $sort | tr $trnl ' '`
cd "$tdir"
: Now see which are supported on this system.
