nope.
if the content is the same, it is the same.

of course I checked with the mentioned svn client.
yes, it does.

I _don't_ suggest that this is functionality to be included in svn.
it is certainly not, because it is not portable,
and it may contradict what people may expect.
but if you know what you are doing (you explicitly use this hardlink script, so you should),
it can consolidate lots of megabytes. and since this script makes this very easy,
I thought I'd share.
of course, if you have a valid reason not to use it, tell me.
I for sure do not want to screw up my WDs, or even repositories.
thanks,
