Subject: Only add extra "points" for a subject with entities when the entities are
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=c2f884176a3ad12ccac9368cf11e6ff9e54d92e6;p=squirrelmail.git

Only add extra "points" for a subject with entities when the entities are
within the remaining range after trimming. This prevents entities at the end
which are cut off anyway to influence the cut-off-point for the subject.
