+// This version of basic_stringbuf relies on the internal details of
+// basic_string. It relies on the fact that, in this implementation,
+// basic_string's iterators are pointers. It also assumes (as allowed
+// by the standard) that _CharT is a POD type.
+
+// We have a very small buffer for the put area, just so that we don't
+// have to use append() for every sputc. Conceptually, the buffer
+// immediately follows the end of the underlying string. We use this
+// buffer when appending to write-only streambufs, but we don't use it
+// for read-write streambufs.
