Subject: makepkg: checkout a revision specified in SVN fragment in
 download_svn.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously the sources were dowloaded in HEAD revision in the download_svn().
If a specific revision was requested in fragment, the code was updated to that
revision in extract_svn(). However, because SVN is a centralized system,
this means that the changed sources has to be downloaded again.

By moving the fragment handling to download_svn(), we get the correct revision
without having to download it later in extract_svn().
