True, but many humans tend to attach meaning to names, to remember
them, and to refer to them. For example, names often appear in the
contents of other files. They just have a tendency of cropping up
here and there. People might find it useful if Subversion had
better support for this.

It doesn't have this functionality right now. You'd have to parse
the output of "log -v", yes. It's onerous on both the server and
the human.

It would work, somehow. I'm aware of that. I'm just imagining a
more convenient feature that also performs better. A lookup
instead of a scan.
