    undo: Take and keep track of the buffers an UndoSequence references · eb614e7f

    We're using weakrefs here because I'm paranoid about the lifecycle
    issues with GTK+ + Python refcounting fun.
    Starting a group now means dereferencing and re-referencing these
    buffers, which isn't great, but is probably the least-bad option. The
    other choice here would be to give groups a reference to their parent
    UndoSequence, and have the buffers lookup follow that, which seems...
    more complicated and confusing.
