From 2042b79bcc7904afc195103dfa1fc6b3978d60f7 Mon Sep 17 00:00:00 2001

Subject: makepkg: add support for SVN urls

Allow SVN repo sources in the form:

source=("<folder>::<repo>#<fragment>")

where <repo> must start with svn (e.g svn+http://) and a <fragment>
can specify a revision (e.g. revision=22).
