annotate tests/test_util.py @ 148:0c5f6420a8b5

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
tests: Add an environment variable (HGSUBVERSION_TEST_TEMP) which allows specification of where temporary repositories (both hg and svn) should be created. Set it to a RAM disk to make the tests run faster.
