[PATCH, svnmerge] Import new larger testsuite

[Giovanni Bajo <ra...@develer.com>]

Hello,

this patch imports a new larger testsuite for svnmerge, which tests actual
functionality of the program. I had been this around for a long time and
used it to collect testscases for bugs already fixed, but I haven't had time
to clean it up for submission. It was time to do it!

Committed as r18342.

[[[
Import a new testsuite which does a complete check of svnmerge
functionalities. The previous testsuite was just unittesting small pieces of
code, while this new testsuite setups a test repository, actually performs
svnmerge operations in it, and check the results.
Moreover, the testsuite is now Python 2.0-friendly.

* contrib/client-side/svnmerge_test.py:
  (True,False): Define for compatibility if not defined already.
  (TestCase_kwextract.test_failure): Test also without space at the end of
  the string.
  (TestCase_RevisionList.test_iter): Disable if iter is not available (pre
  2.2).
  (TestCase_SvnMerge): New base classes for tests which need to call
svnmerge.
  Also provide support for regexp matching on the generated output.
  (TestCase_CommandLineOptions.test_help_commands): Test more forms of the
  help.
  (TestCase_CommandLineOptions.test_version): Make it work on pre-2.2.
  (TestCase.testOptionOrder): New test, verify that options can be
intermixed
  with positional arguments in any order.
  (temp_path, rmtree, template_path): New support functions.
  (TestCase_TestRepo): New complete testsuite, which setups a test
repository
  and use it to test real svnmerge execution. The generated output is then
  tested to verify the functionalities.
