If the goal is to write the code manually as small and elegant as possible then it can be improved IMHO :) It was long time since my last low level x86 codding (damn - 15-20 years?) and the code can be wrong but hope that you'll get the idea. Back then one of my favorite hacks were based on x86 instruction but in this case don's see any benefit to use it.
The current 254-character limit on the size of the output seems arbitrary and not useful. If the limit is to be kept (e.g. because it needs https://github.com/kelseyhightower/echo/issues/3 to be fixed to be lifted) then should exit non-zero when this limit is exceeded.
Recent fixes
Command should return non zero code in case of failure From HN comment: ``
echo command prints all arguments, not just first one
write syscall returns number of bytes written which could be different from argument string length
