Subject: [PATCH] BUG/MINOR: sample: fix the closing bracket and LF in the
 debug converter

The closing bracket was emitted for the "debug" converter even when the
opening one was not sent, and the new line was not always emitted. Let's
fix this. This is harmless since this converter is not built by default.
