Ah! I see what you mean. Is there any way around it though? If I check
the length of the string, either by using strlen(), or a routine of my own
making, won't it break on non-null-terminated strings too (the only way I
can see of doing it is to loop through the string until I find a NULL)?

I totally agree with this. Perhaps I'm missing something obvious here - I
think I need to go to bed :-)
