Intuitively this looks like a place where you'd want to use strlen()
instead of sizeof().  I know sizeof() is faster.  It doesn't make as much
sense as strlen() in this context though.  I suspect that Megamax is
resolving the reference to a string constant as a (char *) which is of size
4.  It's almost funny but some of the 3B compilers also return 4 for this
operation and trying to solve the bug it introduced into our code was the
cause of much wailing and gnashing of teeth.  If you want the length of a
string use strlen().  Personally I think it's a bug if sizeof("string")
doesn't return the size of (char *).
