Do you mean "smaller" (not "bigger")?

Hmph.
In your discussion (including the comment), you talk about "shallow
root" (I think that is the same as what we call "shallow boundary"),
but in this added block, there is nothing that checks CLIENT_SHALLOW
or SHALLOW flags to special case that.
Is it a good idea to unconditionally do this for all "have"
revisions?
Also there is another loop that iterates over "have" revisions just
above the precontext. I wonder if this added code belongs in that
loop.
