[committed] libstdc++: Document when std::string::shrink_to_fit was added

[Jonathan Wakely]

Pushed to trunk.

-- >8 --

This section can be misread to say that shrink_to_fit is available from
GCC 3.4, but it was added later.

libstdc++-v3/ChangeLog:

	* doc/xml/manual/strings.xml: Clarify that GCC 4.5 added
	std::string::shrink_to_fit.
	* doc/html/manual/strings.html: Regenerate.
