annotate tests/test_revmap_migrate.py @ 1549:8410a978c650

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
compathacks: be compatible with upstream 8a0cac20a1ad memfilectx change See hg change 8a0cac20a1ad. Since the interface has changed more than one time, switch to explicit keywords arguments to avoid surprises. Since hgsubversion targets hg >= 3.2.4, drop support for hg 3.0 and 3.1 here.
