Thanks, that is the kind of things casual contributors like me usually
forget.

Seems already checked. Last /usr/dict/words was originally the return value
when nothing is found and has been removed.

Regarding the `ispell-alternate-dictionary'/`ispell-complete-word-dict'
duality I am modifying `ispell-complete-word-dict' default value to nil and
using 

  (or ispell-complete-word-dict
      ispell-alternate-dictionary))

for previous standalone calls of any of both variables. That way
`ispell-complete-word-dict' is only used if explicitly set and
`ispell-alternate-dictionary' is used otherwise. If they are ever used 
for something different this should not disturb and leave things ready.

For those curious, I am attaching a diff with my current changes. Will check
a bit more and if no further problems are found will commit to trunk
tomorrow to allow for wider checking of changes.
