I often work on several projects at once, using a *vc-dir* buffer for
each.

If I type "l" in this buffer, I get a *vc-change-log* buffer with the
history of the project.

However, all calls to vc-print-log use this same buffer.
This seems to be hard-coded in vc.el (vc-print-log-internal).

I would like to be able to make it so that each use of "l" from a
*vc-dir* buffer gets its own *vc-change-log* buffer; and that "C-x v l"
in some source file gets a separate buffer.  This way the per-project
change-log buffers could be relatively long-lived; as it is recomputing
the data in them takes much too long.
