An improvement to offline receipts

[joanne]

http://forum.civicrm.org/index.php/topic,33160  has prompted this suggestion.

My organisation has a rule of "donation received via post -> receipt sent via post" but obviously not all organisations do.  Customising the system workflow message templates can be a bit daunting for some users/administators. 

I think it would really help if the off-line contributions receipt could be altered so that when an off-line donation is associated with a particular online contribution page the receipt message entered  on Thank-you and Receipting for that contribution page is included in the off-line receipt.

What do others think?
