I was tried to solve this problem a few times but all solutions were
over complicated. One of the possible solutions is to run 'plink.exe -v'
and monitor all its input and output to catch possible password prompts.
But then I've realized that I was tried to solve a wrong problem. Now I
think the right problem is not try to monitor all plink's dialogs for
possible password prompts (I believe it's not possible to do reliable)
but just print the right error in case of the problem.

The attached patch adds '-batch' option to plink and now plink closes
the pipe if unable to open ssh connection and standard connection error
can be reported.
