This did occure to me, hence the option 3). svn add *must* already check
to see if the vile was previously versioned, as it throws up "this file
is already under version control", option three would just mean extening
that bit of code to give users a choce to keep versioning the file.

It was a directory structure, but only a small one, the main problem
though is this is my /etc directory that is being versioned, so files
are put back by outside tools so the svn copy -r..... cannot really be
run first.

Granted, I tend to treat it more as snapshots of this file tree, which
is useful for me, but does lead to these little descrepancies.
