src/bin/echo/echo.c contains a part of code which to my opinion is not good, because contains "if" in "while". It is slow. So I send you my version of that part.

Old part:
        while (*argv) {
                (void)printf("%s", *argv);
                if (*++argv)
                        (void)putchar(' ');

My version:
        if (*argv)
                (void)printf("%s", *argv++);
        while (*argv)
                (void)printf(" %s", *argv++);

I do understand that it is only small improvement but I hope it's just the beginning. :)
