2 - simplify find_branches by using Transport.list_dir() ?
3 - replace 'undefined' by scheme name in revision ids
4 - fix commits in heavyweight checkouts somehow
5 - fix autorealm repository
6 - handle parent directories of branches being moved correctly
7 - faster "bzr status" in lightweight checkouts
8 - when committing specific files in a lightweight checkout, make sure to
9 commit the right file id changes for "."
10 - custom implementation of WorkingTree.revert()
11 - don't update all entries to the same revnum when opening working tree
12 - avoid extra connect in logwalker?
13 - make ListBranchingScheme() support wildcards
14 - rewrite TrunkBranchingScheme() and ListBranchingScheme() as subclasses of
16 - more efficient implementation for applying txdeltas to weaves. perhaps convert svn deltas to bzr deltas?
18 - implement BzrDirFormat.get_converter()
19 - report changes to delta editor in Branch.pull()
20 - add tests for objects returned by WorkingTree.pull(), Branch.pull()
22 - split fetch tests out of test_repos
