[s-xml-rpc-devel] Patch

[Maciek Pasternacki]

Hello.

I started to look at s-xml-rpc library today and to communicate with
Python client.  Python's default xmlrpclib sends no-argument methods
like this (from debug log):

,----
| <?xml version='1.0'?>
| <methodCall>
| <methodName>system.listMethods</methodName>
| <params>
| </params>
| </methodCall>12 received call ("system.listMethods" . "
| ")
`----

Library throws error from #'APPLY because last argument is a string,
not a list.  A simple patch that makes it work:

#v+ diff -u xml-rpc{-orig,}.lisp
