Description

For instances the dialog for storing a yet unknown host key. Heidi shows a prompt with yes/no/cancel buttons:

Pressing yes should send a "y" to the running plink process, while pressing no should send a "n". Both are sent to the input pipe which is connected to the plink process, but both are ignored for some reason.

Obviously, this is related to changes in plink 0.82 with the new -legacy-stdio-prompts parameter, supported in #2118 .
