regexp in attr-rewrite confuses me!

[Tariq Rashid]

i'm finding counterintuitive behaviour for the regexp in the "searchfor"
attr_rewrite. i have the following
        attr_rewrite attr_rewrite_post-proxy {
                attribute = Framed-Route
                searchin = proxy_reply
                searchfor = "([0-9./]+) ([0-9.]+) ([0-9]+)(.*)"
                replacewith = "[%{2}]"
                new_attribute = no
                ignore_case = no
                max_matches = 1
                append = no
      }

so for a Framed-Route of "83.67.67.192/29 83.67.214.161 1" it should give
me:
        %{1} = 83.67.67.192/29 83.67.214.161 1
        %{2} = 83.67.214.161
        %{3} = 1

but instead %{2} contains "83.67.214.161 1".

see the radiusd -X logs:

modcall[post-proxy]: module "attr_filter_post-proxy" returns updated for
request 0
radius_xlat:  '([0-9./]+) ([0-9.]+) ([0-9]+)(.*)'
radius_xlat:  '[83.67.214.161 1]'
rlm_attr_rewrite: Changed value for attribute Framed-Route from
'83.67.67.192/29 83.67.214.161 1' to '[83.67.214.161 1]'

anywone know why this is?

also the \d for [0-9] don't work!
