Order in output of "bzr status -S -r"

[Eli Zaretskii]

"bzr status -rR1..R2" shows the files that were
added/removed/renamed/modified between the two specified revisions.
It shows them nicely ordered alphabetically in each category.

By contrast, "bzr status -S -rR1..R2" does not keep that order, and
instead shows the files in some seemingly random order, which makes
the output less convenient for human consumption.  Is this on purpose,
or should I file a bug?
