Also right now two committers can be committing to different parts of
the tree at the same time, so A might get his src commit in first, but
get the second serial because B races his commit in and wins the race
for the global serial number.
So the serial number is only approximately useful, but that
approximation is likely to be better than 4.4 or 4.5 :-).
Right now cvs co -D doesn't work due to repo surgeries, and this would
be no different.
As to the format, ignore everybody else and pick one that won't
generate too many complaints. I have my opinions, but that's really a
detail best left to the implementor. (eg I don't care what you do as
long as it isn't Wrong :-).
