10114	Incorrect position of partial match when using u32regexes	mkrasowski@…	John Maddock	"Hi,

I got a problem with results of partial matches when using  
ICU Unicode strings and u32regex_iterator. The regular
expression is created with default flags and search is done 
using match_perl | match_partial. Tested on 64bit Linux, boost compiled against ICU 53 with gcc 4.9.

When searched for regular experession: ""summary""
in string ""in summary in math we are using sum"", and for 
regular expressions based on std::string got the following results:

match length: 7 match position: 3  matched: summary
match length: 0 match position: 32 matched: sum

when doing search using icu::UnicodeString and u32regex_iterator
got the following result:

match length: 7 match position: 3 matched: summary
match length: 0 match position: 35 matched:

So in both cases the partial match is found but in the latter the returned 
position is incorrect. 

I attached a simple application I used for testing.
