How about a set of patches:

1) Change SVN with your aforementioned reasoning.
2) Change SVN to use "cp -au" if the directory exists in $srcdir
3) Have git update itself rather than delete
...

We will deal with hg/bzr once we have git working properly.

For git, the solution appears to be to always to do the "git checkout
-B" if it is being updated, regardless of if it has a commit/tag/branch
reference or not.  So the check will be:

if [[ -n $ref ]] || (( updating ))

where "updating" records whether or not there was a git checkout in
$srcdir in the first place.
