New Revision: 927536

URL: http://svn.apache.org/viewvc?rev=927536&view=rev
Log:
Add a new function to append a skel to a (list-)skel.

* subversion/include/private/svn_skel.h:
  (svn_skel__append): new declaration

* subversion/libsvn_subr/skel.c:
  (svn_skel__append): ensure we're looking at a list skel, and then hook
    the new skel into it.
