Why do you think so?  Have you tried it?  It does not affect
the behavior for THING = `symbol' at all.

So?  Not a problem.  Put point after a symbol - you get the
same answer as now.

This is the design of the thingatpt code, and the reason why
`<=' instead of `<' is a bug: 

  the function that is (get THING 'end-op) moves PAST the THING,
  so that point is not on the THING.  This is true generally, no
  matter the type of THING.
