 1.2.4 too ... someone needed a course in defensive programming... there are
 lots of tests below for temp != NULL, but what is desired is *temp != '\0'

 which are must faster as *temp != constant ...

 Anyhow, the test case I've got that's core dumping is:
    <META content=3D"MSHTML 5.00.2614.3401" name=3DGENERATOR>
 no trailing quote, no trailing space... and with the missing/broken check for+  end of string it scribbles over the stack...
