As of trunk r29013 only for svn:author and svn:date.

The current svnsync code on trunk will include all revprops with the
commit, except the two you mention. So on post-commit you'll have all
info expect author and date.

As a workaround for your problem, you can use some knowledge about the
internals of svnsync. Before starting to copy the revision contents,
svnsync will set a revprop called 'svn:sync-currently-copying', which it
will remove right after the svn:date and svn:author revprops are copied.
So, write a post-revprop-change hook that checks for the removal of this
revprop, takes the revision argument and uses svnlook to read all needed
info from the repository.
As it depends on the way svnsync is implemented - which may change - I
wouldn't call it a solution, but at least it can serve as a temporary
workaround.
The most decent solution IMHO would be to allow passing the svn:author
and svn:date revprops on commit.
