+Subject: [PATCH] Skip extra newline when run from scripts
+
+A user can use an invocation like `echo 1234 | stoken --stdin tokencode`
+to run stoken from a shell script.  This currently outputs an extra
+newline character because that is necessary for interactive prompts,
+making it harder to parse the output.  Skip the newline if stdin is not
+a tty.
+
+Fixes #29.
