[PATCH 2/4] contrib: pick: move the insertion of fields up a level

[Mark Walters]

This moves the actual insertion of message fields up from the field
formatting function into the message insertion function. This will be
useful in the next patch as we can apply further formatting to the
insertion string before inserting.
