Bug fix: line separators in marshall()

[Ryo Neyama <ne...@trl.ibm.co.jp>]

There is some inconsistency about printing line separators in the
following codes:
      Envelope#marshall()
      Body#marshall()
      RPCMessage#marshall()
More specifically, while Body#marshall() prints line separators before
and after body entries, RPCMessage#marshall() does NOT print a line
separator after the last body entry.

This causes a problem in combination with SOAP digital signature
because info set of the target envelope is broken in marshalling and
unmarshalling.

The patch to fix the above problem is as follows:

I'm going to commit this patch if there is no objection on this in few
days.
