The thing to remember is that arch doesn't keep per-file history _at all_ --
log files are associated with changesets.

In many cases, this is actually more useful than a per-file history, but
sometimes you do want to see that.  As it turns out, there's enough
information kept in the changeset logs that you can easily (and
automatically) track a file's evolution through a series of changesets.

I have a shell script (`tla-file-log') that does this and emits cvs-style log
output.  However, in practice I find I rarely use it; more often I just want
to see the overall branch history.
