OK, but almost by defintiion, if you can afford to have a sources file on
your system (given Dan's most excellent  disassembling with temp names
sourceless scheme) you can afford to have a large sources file.  So why not
keep the history on the sources file, keeping the system self-contained-ish,
and preserving the ability to browse history without an internet connection,
etc, etc?   Then don't you already get to use the infrastructure for
browsing versions on the change log?
