| Yes. I think the test is obsolete.

Yes, I changed the behavior of char() for Matlab compatibility.  I
also changed the tests for char in strfns.cc to match but missed the
ones in test_string.m.  Carlo, your change is correct, but I would
like to move all the tests from test_string.m to the source files so
the tests are with the source code for the functions they test instead
of in a separate file where they can easily be missed.  Then we can
remove test_string.m.  I can make this change later today.
