Import problem with large AS Sets in 4.8.5

Hi,
Okay, one more odd problem with 4.8.5 (apologies for the large email) 
that I hope someone can help me with.

If you have a peer with a large AS-SET then the output when it needs to 
create split lines for as-path access-lists on a Cisco is a bit wierd.

It looks like this broke first in 4.8.2:

With a policy of:

import:         from AS65525 10.1.1.1 at 10.2.2.2
                   accept <AS-FLAGP>

For example with 4.8.1 we get the result we'd expect where it's split 
appropriately:

# RtConfig -h 203.16.214.210 -p 43 -protocol rawhoisd -config cisco 
-cisco_use_prefix_lists -supress_martian
 > @RtConfig import ASXXXX 10.2.2.2 AS65525 10.1.1.1

4.8.1:
no ip as-path access-list  1
ip as-path access-list 1 permit 
_(112|151|250|702|1140|1200|1290|1830|1836|2009|
2018|2042|2129|2277|2561|2571|2609|2612|2687|2697|2706|3092|3095|3225|3291|3300|

_
ip as-path access-list 1 permit 
_(4618|4641|4645|4651|4653|4655|4658|4745|4747|4
748|4750|4760|4761|4762|4766|4767|4775|4780|4791|4801|4823|4844|5080|5384|5385|5

ip as-path access-list 1 permit

(... etc)

With 4.8.2 and above though we get a result where it looks like it:
(1) puts an "@" first
(2) Dumps the whole AS SET
(3) Then puts the bit which should have only just been there.

no ip as-path access-list  1
ip as-path access-list 1 permit
