What is the semantics of "bzr checkout ../fix$i" in this case?  What
does it do, exactly?

Bazaar docs are not very clear on that, to say the least:

    Purpose: Create a new checkout of an existing branch.

But fix$i is already an existing branch, and one with local changes,
so this ``create'' seems not quite the right word here.

    Usage: bzr checkout [BRANCH_LOCATION] [TO_LOCATION]

    Description: If BRANCH_LOCATION is omitted, checkout will reconstitute
		 a working tree for the branch found in ‘.’.
		 [...]
		 If the TO_LOCATION is omitted, the last component of the
		 BRANCH_LOCATION will be used. In other words, “checkout
		 ../foo/bar” will attempt to create ./bar. If the
		 BRANCH_LOCATION has no / or path separator embedded,
		 the TO_LOCATION is derived from the BRANCH_LOCATION
		 by stripping a leading scheme or drive identifier, if
		 any. For example, “checkout lp:foo-bar” will attempt
		 to create ./foo-bar.

Again, ``create ./bar'' sounds incorrect in the context of your
suggestion.  ``Reconstitute a working tree'', OTOH, sounds too obscure
to help.

So what does this "checkout" do in this case?

(Btw, note the tricky convention regarding slashes, not for the faint
of heart IMO.)
