Comment(by karsten):

 After talking more to asn on IRC, we came up with a slightly more paranoid
 variant:

  - Sanitize `transport` lines by only keeping the `transport SP
 <methodname>` part.

  - Remove `transport-info` lines entirely.

 Reasons are that it's yet unclear what the `arglist` part will contain in
 future transports.  As a result, we also drop `transport-info` lines
 completely.  asn further had concerns about not sanitizing the `port`
 part, so we left out `<address:port>`.
