Re: Check Client Version in hook

[Stein Somers]

Just be aware that these hooks disallow all commits, not just commits of 
merges, where the svnbook advice applies. There's not much better you 
can do, because it's impossible to tell from an "old" transaction if it 
contains a merge or only genuine, original changes.

If you'd still like to allow old clients to commit particular kinds of 
changes (like tagging), or in particular branches, it's not that easy.
