This is a distilled version of what I plan to check in:

1         std::string     string_with_nulls ("123 \0 456", 9);
2         std::stringbuf  sbuf (string_with_nulls);

sbuf.str().size() should be 9, but right now, it's only 4.  The user in
the original bug report was constructing (indirectly) a string like the
one on line 1.  But inside istringstream, when we created its stringbuf
with something like line 2, we were allowing a strlen() call to determine
how much data to copy.
