Bread-Bakers v117.n041.6

There was an error in the serving size of the Preston Rolls recipe in 
the Oct 15, 2017 digest (v117n039). It should be 24 instead of 12.

The recipe in the archives 
<https://bread-bakers.com/msgs/v117n040/msg00002.html> has been 
corrected. Thanks to Deb Rogers for informing us.
