* Nathan Myers <ncm@cantrip.org>.
*
*
* This approach has the enormous advantage that a string object
* requires only one allocation. All the ugliness is confined
- * within a single pair of inline functions, which each compile to
- * a single "add" instruction: _Rep::_M_data(), and
+ * within a single %pair of inline functions, which each compile to
+ * a single @a add instruction: _Rep::_M_data(), and
* string::_M_rep(); and the allocation function which gets a
* block of raw bytes and with room enough and constructs a _Rep
* object at the front.
*
- * The reason you want _M_data pointing to the character array and
+ * The reason you want _M_data pointing to the character %array and
* not the _Rep is so that the debugger can see the string
* contents. (Probably we should add a non-inline member to get
* the _Rep for the debugger to use, so users can check the actual
* string length.)
*
* Note that the _Rep object is a POD so that you can have a
- * static "empty string" _Rep object already "constructed" before
+ * static <em>empty string</em> _Rep object already @a constructed before
* static constructors have run. The reference-count encoding is
* chosen so that a 0 indicates one reference, so you never try to
* destroy the empty-string _Rep object.
*
* All but the last paragraph is considered pretty conventional
* for a C++ string implementation.
