[10] RFR 8184706: Matcher doesn't indicate hitEnd after matching \u0D with \R at EOL

[Ivan Gerasimov]

Hello!

It was spotted that in certain situations the Matcher.hitEnd() returns 
false, though the regexp engine in fact has hit the end of the input.
This is because the \R pattern can match both 0x0d and 0x0d0x0a 
sequences.  Thus, the engine "hits the end", if the input ends with 
0x0d, since the engine wants to greedily consume 0x0a.

Would you please help review the fix?
