Yes, this is a fairly serious problem.  We need to refine the
`print-log' backend op to be able to control it somehow.  E.g. in
vc-annotate, it'd be good to be able to get just the log message
corresponding to a particular commit.

For a generic `vc-print-log' operation where the user doesn't specify
any particular revision, I wonder what the best UI should be.  What do
other front-ends (e.g. loggerhead, viewCVS, ...) do to cope with the
large number of log messages?

Maybe we should show just the first thousand or so by default and then
provide a button (and command) in log-view-mode to get more?
