spellchecker: compensate for aspell error and blocking problems

Sometimes Aspell seems to output not enough blank lines to signal
a line change. This patch tries to compensate for this by trying
the next two lines as well.
This patch also fixes a problem were reading from aspell could
produce a deadlock on the socket and would cause the spellchecker
to never return
