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.

Setup:
|
|
|
|
create a little extension that has 3 side-effects:
|
|
1) ensure changelog data is not inlined
|
|
2) make revlog to use lazyparser
|
|
3) test that repo.lookup() works
|
|
1 and 2 are preconditions for the bug; 3 is the bug.
