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?

I think so (then, the patch LGTM).

Tom might want to weigh in on this, though.

Dmitry> Tom might want to weigh in on this, though.

I don't really have an opinion.
The proposed behavior seems fine to me.

Tom

Or maybe retain the old behavior on using a prefix arg?

I.e. C-u M-x vc-print-branch-log could ask for a directory,
with the default on default-directory.

Personally, I don't remember needing something like that (or, in a 
once-a-decade occurrence, I can use the console). But if you find it 
useful, sure.
