That's about the way I feel about it, too. I wanted to avoid those
hairy RCS-style numbers, but it ended up being the easiest way out.

I've found CVS's behavior annoying. Red Hat's GNU toolchain
repository has 232 branches, which are almost all irrelevant to what
you want, since all but one don't apply to the text at hand.

What the behavior I've described above lets you say is, "What is the
history of *this* piece of text?" Which, at least for me, is the
question I'd rather be asking.
