And the problem I've already mentioned concerning previous versions
is still there:

$ svn diff -c3876 file:///home/vlefevre/private/svn-mpfr > mpfr-diff
$ svnadmin dump --incremental --deltas ~/private/svn-mpfr -r3876 > mpfr-dump
* Dumped revision 3876.
$ ll mpfr-diff mpfr-dump
-rw-r--r-- 1 vlefevre vlefevre 2590 2012-06-21 15:03:53 mpfr-diff
-rw-r--r-- 1 vlefevre vlefevre 9333 2012-06-21 15:03:54 mpfr-dump

where the dump contains data that haven't changed, thus are useless
in a dump.

Or you can try directly:

$ svn diff -c3876 svn://scm.gforge.inria.fr/svnroot/mpfr > mpfr-diff
$ svnrdump dump --incremental -r3876 svn://scm.gforge.inria.fr/svnroot/mpfr > mpfr-dump
* Dumped revision 3876.
$ ll mpfr-diff mpfr-dump
-rw-r--r-- 1 vlefevre vlefevre 2590 2012-06-21 15:13:54 mpfr-diff
-rw-r--r-- 1 vlefevre vlefevre 9210 2012-06-21 15:13:24 mpfr-dump
