It used to work in Emacs 24, and I have come to rely on that behavior.
Apparently the fix for bug #19084 changed it, vc-deduce-fileset in the
*vc-change-log* buffer no longer returns the file whose history is
displayed, but rather the directory it is in.

Not explicitly, but I find it a bit surprising (and annoying) that the
command to list the changelog of a fileset does not preserve that same
fileset in the log buffer.

Certainly the behavior of C-x v L is more correct now, but the one of
C-x v l has regressed.

That's the least I would expect.
