I think the best way to handle this would be:
* Restore the old repository
* Commit dummy padding revisions into the repository to bring the revnum up
to 1233
* Check out a new wc
* Make a script to copy every file *ignoring the .svn directories* from your
laptop wc into the new wc, replacing the versions that are there.
* Run "svn add", "svn rm", as needed.
* Commit the new wc.
Other developers who also had a wc all at 1234 could carry on working, *BUT*
if anyone has a wc corresponding even in part to one of the lost revisions
(now dummy padding revisions), then any update operation will likely fail.
They will need to check out a fresh wc, and port any changes out of the old
wc, then delete it.
Max.
