** Source:  test1.c
**
** Purpose:
** Ensure that this function moves the string pointer ahead one character.
** First do a basic test to check that the pointer gets moved ahead the one
** character. Then try with an array of bytes and a NULL array.  Each of 
** these should still work by returning a pointer to thePointer+1.
**

/*
 * Note: it seems like these functions would only be useful if they
 *   didn't assume a character was equivalent to a single byte. Be that
 *   as it may, I haven't seen a way to get it to behave otherwise.
