Accidentally I noticed that vc-print-branch-log prints a narrower log
than it should.  I don't remember any damage from this data loss
but this is not the right thing to do - by default it should show logs
from the repository root, not logs limited to a subdirectory when
this command happens to be called from a subdirectory.

Am I correct to expect that vc-print-branch-log should print
log from branch's root like vc-print-root-log does, and
not from a subdirectory like vc-print-log does?
