branchcache: gather new obsolete revision in a set
This is part of a series to more clearly split the update in two step. This
will allow us to introduce a fast path during update in a future changeset.
Mercurial evolves over time, some features, options, commands may be replaced by
better and more secure alternatives. This topic will help you migrating your
existing usage and/or configuration to newer features.
Commands
