After your last commit, the tiny version shows the full content for the help command. The full version shows the connect
the connect command only. It looks like a compiler issue. It occurs with gcc 8.2.0 only. For gcc 7.3.0, there is no
difference between the tiny and the full version in the output of the help command. My router is a tp-link archer c7
(target system ath79, mips32).
