Eazysvn

-------------------

* New argument: ``ezmerge --accept=ARG``, passed directly to subversion.

* Moved the source code from self-hosted Subversion to GitHub.

-------------------

* A somewhat better error message for ``ezswitch -c newbranch`` when eazysvn
is unable to understand the branch structure (LP446369).

* ``ezswitch -t tagname; ezswitch branchname`` switches to a branch named
``branchname`` instead of trying to switch to a tag named ``branchname``
(LP617888, fix by Wolfgang Schnerring).

-------------------

* Minor fixes to various options --help messages.

* Don't pass revision range to svn when using ``ezmerge --reintegrate``.
Patch by Michael Howitz <mhgocept.com>.

* New option: ``ezmerge --tag``.

-------------------

* New option: ``ezmerge --reintegrate``, passed straight to svn merge.
Contributed by Wolfgang Schnerring <woscwosc.de>.

-------------------

* Uses ``subprocess`` instead of ``os.popen2``; no more deprecation warnings
on Python 2.6.

------------------

* ``eazysvn tag`` accepts the -l (--list) option.
* ``ezbranch`` and ``ezswitch`` accept the -t option.
* New command: ``eazysvn branchpoint``.
* You can refer to tags in all commands that accept branch names; use a branch
named "tags/*tagname*". This works for all kinds of prefixes, e.g.
"obsolete-branches/*branchname*" etc.
