test: use proper subclassing in `test-issue2137.t`. To use changelog filtering on the repository, we plan to use "proxy" object that perfectly mock a repository but with a filtered changelog. Altering the `repo.commit` function using `extensions.wrapfunction` will prevent the logic to propagate to the proxy class by the mean of inheritance. We changes the extension to use subclassing as expectable.

run-tests: remove dead code for supporting old test scripts

run-tests: handle windows crlf in .py tests again Before af7c6bc48d8d all crlf occurrences in test output on Windows were simply changed to lf. In af7c6bc48d8d it was replaced by more clever handling in the .t test runner ... but the .py runner was forgotten and many .py tests were failing on Windows. The crlf/lf replacement is now reintroduced in the py test runner.

test-run-tests.t: fix wrong test case for cr handling on Windows An incorrect and failing test case was introduced in af7c6bc48d8d.

win32mbcs: add reversing wrapper for some unicode-incompatible functions. This changeset fix the problem to use win32mbcs with mercurial 2.3 or later. The problem is brought by side effect of modification of encoding.upper() (changeset 17236:9fb8312dbdbd) because upper() does not accept unicode string argument. So wrapped util.normcase() which uses upper() will fail. In other words, upper() and lower() are unicode incompatible. To fix this issue, this changeset adds new wrapper for reversed conversion (unicode to str) for lower() and upper() to use them safely.

convert: normalize paths in filemaps (issue3612) convert doesn't normalise double slashes in paths. Path normalization is applied when a path is loaded into filemap and when a file lookup request is issued to filemap.
