Merged requested to merge bitbucket/merged-pr-531 into branch/default
Created originally on Bitbucket by natebragg (Nate Bragg)
Was already merged in Bitbucket before import, marked as merged by the import user
Failing test showing that lstrip doesn`t consume a whole string.
If possible, make lstrip consume the whole string.
Previously, it would not consume the final character even if it matched, because rpos pointed to the final index.
