+Subject: Fix PuTTY interop tests
+
+A while back I got a patch into PuTTY (although it hasn't yet made it
+into an upstream release) to add passphrase-file options to puttygen.
+Use these to make the PuTTY interop tests non-interactive.
+
+Fix up a few details of the saved session.
+
+When plink is given a saved session name, it expects that *instead* of
+the host name (or IP address), not in addition to it.  Drop "127.0.0.1"
+from the various plink test command lines.
+
+(It is possible that the last two of these represent compatibility
+breaks of some kind; but if they are, then that ship sailed sufficiently
+long ago - at least seven years, possibly more - that it's no longer
+worth worrying about it.  It's more useful to test interoperability with
+current versions.)
