+Subject: [PATCH] upstream: check in scp client that filenames sent during
+
+remote->local directory copies satisfy the wildcard specified by the user.
+
+This checking provides some protection against a malicious server
+sending unexpected filenames, but it comes at a risk of rejecting wanted
+files due to differences between client and server wildcard expansion rules.
+
+For this reason, this also adds a new -T flag to disable the check.
