lost doc link to enable_shared_from_this

[kab@…]

In boost 1.53 I can't find any reference to the documentation forenable_shared_from_this. The documentation page exists:

http://www.boost.org/doc/libs/1_53_0/libs/smart_ptr/enable_shared_from_this.html

but I can't find any reference to it from anywhere in the smart_ptr / shared_ptr documentation. As late as boost 1.52 there was a reference to it in a note for the

template<class Y> explicit shared_ptr(Y * p);

constructor, but that note was removed in boost 1.53, and there doesn't seem to be any other reference to enable_shared_from_this. One of the places I expected to find a reference to enable_shared_from_this was the "Programming Techniques" page's entry "Obtaining a shared_ptr from a raw pointer", but I found no mention of it there through boost 1.53.

(In [84506]) Document that constructors initialize enable_shared_from_this. Refs #8573.

enable_shared_from_this is mentioned in the Programming Techniques page, but in a later entry: http://www.boost.org/doc/libs/1_53_0/libs/smart_ptr/sp_techniques.html#from_this

[Peter Dimov]

(In [84507]) Merge [84506] from trunk: Document that constructors initialize enable_shared_from_this. Fixes #8573.
