+Fix "Hostname" parsing in OpenSSH config files, as reported
+at <https://red.libssh.org/issues/260>.

+Subject: [PATCH] Fix reading of the first parameter
+
+This is a fixup for 7b8b5eb4eac314a3a29be812bef0264c6611f6e7.
+Previously, it would return as long as the parameter was _not_ seen
+before. It also did not handle the case for the unsupported opcode (-1)
+which would cause a segfault when accessing the "seen" array.
