[boost] Misbehaviour of boost.regex

Hi *, 

I think I stumbled across a bug in boost.regex, but perhaps it is just 
me misunderstanding the docs. Basically it seems like regex_match breaks
its postcondition when working with std::string input and smatch result.

Attached is a new test case for the test suite (my first trial, I bet it
does not fit into boost unchanged) which shows the bug (if it is one). 
Interestingly, using regex_match together with a const char pointer and 
cmatch results works like expected.

I attached the new source file, which belongs into
boost/libs/regex/test/regress together with changes to the Jamfiles as
a diff.

Any comments welcome. 

Greetings
