test-log-linerange: open binary file in binary mode The '\n' characters were being translated on Windows, throwing off hg and git hashes, as well as the file content in the diff.

test-arbitraryfilectx: stabilize for Windows Previously, the second last test (context.arbitraryfilectx(..)) returned True on Windows. I changed the repo setup sequence to import a patch, so that way the repo would have a proper symlink. That made the last test fail, since it is comparing files in wdir(), one of which is not the expected symlink. Apparently the (feature !) line matching doesn't work well with (no-eol), so I had to conditionalize the test instead of the output.
