The problem with $Log$ (and one of the reasons that it's discouraged
these days) is that there is no clear end to what it's inserted into the
file. I think that the only guarantee is that you'll have the same
comment character on all following lines. Which isn't much help if
you've got comments immediately after $Log$ anyway.
To be honest, I'd say that you're probably better off simply running the
svn conversion as-is, then doing one big cleanup on all the files.
Commit it all in one go and then stop worrying about it. Disk is cheap.

This is exactly how the SCCS to RCS conversion script works. :-)
