VPP-27 Extend telnet protocol buffer guard
With Telnet protocol overhead, the string "xterm-256color", which is the norm when the terminal is iTerm on a Mac, is longer than the 16 byte lookahead overflow guard in the Telnet protocol processor. This extends it to 24 bytes. This guard is designed to encourage the protocol processor to quit waiting for bytes indefinitely if those already in the buffer do not form a complete message. Whilst this is unlikely, extending the guard length would mean more bytes need to be received before it gives up.
