Are squashed commits and discarded branches possible in bzr?

Git uses a few bytes, indeed (IIUC it's just a single file containing
the sha1 of the revision referred).  Bzr instead uses several files
inside a couple of directories, and this includes extra data such
a branch.conf and a copy of the tags (in Emacs's case the tags amount
to about 70KB nowadays).
So while it may not be humongous, it's clearly "a lot more" (like 1000
times more for Emacs branches).

I don't think that's what he meant.
