repocutter: multiple node selection broken within single revision

1b4e8dd7

only 1.1 is selected

cat test/vanilla.svn | ./repocutter -q -r 1.1,1.2 select | repocutter -q see
1.1   add      branches/

this works

cat test/vanilla.svn | ./repocutter -q -r 1.1:1.2 select | repocutter -q see
1.1   add      branches/
1.2   add      tags/

makes it impossible to select nonconsecutive nodes (f.e 1.1,1.3) in single repocutter instance.
