It looks like internal spaces are used in \alias entries,
e.g.,
./R.utils/man/Non-documented_objects.Rd:\alias{Non-documented objects}
./SparseM/man/character-null-class.Rd:\alias{character or NULL-class}
I think the trailing spaces are intended to be ignored,
so a better fix would be
--- Rdlists.pm (revision 42846)
+++ Rdlists.pm (working copy)
