of strings. We mostly did the Right Things already; I simplified the code a bit and also had us not write to more characters in the C bindings than we're supposed to (per language in the MPI-2.1 spec). Fixes trac:1238. This commit was SVN r18705. The following Trac tickets were found above: Ticket 1238 --> https://svn.open-mpi.org/trac/ompi/ticket/1238
