It would be possible, but computationally expensive with the current
recorded data.

There are a couple ways to try and "cheat" but they fail with certain
edge cases.

So the way to do it now, is to compute the changes between each revision
and its parent, and see if anything involving the given directory or
anything underneath it is effected.

The code could be cribbed from the 'bzr log -v' which does compute the
delta for each revision.

I personally feel our "bzr log" code is in serious need of an overhaul,
for a variety of reasons. But that is not specifically related.
