Just in case you didn't know, strcat works by looking for the null terminator
on the first (target) string, so the null has to be there anyway.

If you do a strcat(str,"\0"), it should be a null operation (do nothing) since
this is the same as strcat(str,"").

If you do a strcat(str,'\0'), you should get a sore dump, or at least
undetermined results (whats at address 0?).
