Branch: lstrip_to_empty_string
Changeset: r90834:2275619cea33
Date: 2017-03-28 07:10 -0400
http://bitbucket.org/pypy/pypy/changeset/2275619cea33/
Log: 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.
