RFR [6961766]: PrintStream.write() should flush at most once

[Ivan Gerasimov]

Hello David!

Thanks for review.

Sorry, I don't see how the proposed change would contradict the spec .
The code first writes a char[] buffer to an OutputStream, and then 
invokes flush() if the written array contained at least one '\n' char.

In addition to that, the documentation for OutputStream#flush() says: 
"Flushes this output stream and forces any buffered output bytes to be 
written out." Thus, there should be no point to have several subsequent 
calls to flush() with no data writes between them.

I don't insist on pushing this change, but I think it's harmless and may 
be useful.

Sincerely yours,
Ivan
