Memcache save bug was breaking read the rest of the comment

Full text was getting saved to the chopped value memchace var because
the conditional did not include the check to see if we were working on
a full text search.

$possible_chop can’t include the check for full as there is a special
check needed when reading the memcache for looking at full values.
