Weird scm_to_latin1_string() behavior.

Hello,

the attached code produces

$ ./a.out
foo,bar
bar

while I would expect

$ ./a.out
foo
bar

Similar behavior can be produced with `substring', but `substring/copy'
will work as expected.  So I suspect this is some issue with strings
sharing memory and a missing '0' when scm_to_latin1_string calls
scm_strdup.
