Hi,
it seems braceexpand option does not always affect expansions, sometimes
it depends on glob option.
<snip>
Seems braceexpand has no effect. Instead glob options
affects expansion.
a='{1,6}' b='{1..6}'
for i in -braceexpand +glob +braceexpand -glob; do
set ${i%${i#?}}o ${i#?}
set -o | sed -n -e 's/ */ /' -e /glob/p -e /braceexpand/p | tr '\n' '
';echo
print "$a" $a
print "$b" $b
print "{1,6}" {1,6}
print "{1..6}" {1..6}
done

well, braceexpand works ok for static values ({x..y}), but not for
dynamic values ($x), is this intended ?
unfortunatelly, {1..5,6} does partly work w/ braceexpand.
$ set -o | sed -n -e 's/ */ /' -e /glob/p -e /braceexpand/p | tr '\n' '
';echo
braceexpand on glob off globstar on
$ print {1..5,6}
1..5 6
