[PATCH] contrib/subtree: remove contradicting use options on echo wrapper

Remove redundant -n option and raw ^M in call to echo.

Call to 'say' function, a wrapper of 'echo', passed the parameter -n, then
included a raw ^M newline in the end of the last parameter. Yet the -n option
is meant to suppress the addition of new line by echo.
