Hm ... I just found that in r100 I did a couple of other changes to the repository other than adding the big unwanted file, so the recipe I had in mind is not an option.
I am left with your suggestion, svnsync. I thought it was used just to mirror a repository, do you mean it can be used to make a copy of a repo with some changes? What versione of SVN do I need (currently using 1.6.12)? Some users have pre-1.5 subversion; will they be able to checkout from the new, modified repository (if created with --pre-1.5-compatible)?
