According to my ANSI C book strlen() returns the number of characters in
a string NOT including the zero termination character. So I think in that
case you would be indeed off by one.

char test[]="a"
strlen(test) = 1;
test[strlen(test)-1] = 'a'
test[0] = 'a'
test[strlen(test)] = '\0'

char test1[]="a\n"
strlen(test1) = 2;
test1[strlen(test)-1] = '\n'

In this case, my patch overwrites test1[strlen(test)-1] with '\0'

This is what I intend.
