This is extremely usual!  Suppose you have a string where the first character
indicates what kind of string it is, I have this in a big program I'm working
on now.  I therefore often say "dosomething(&string[1])".

In other words, the problem with these kinds of assumptions is that you can
add odd numbers to char pointers to get final substrings.
