pg_waldump: Fix --bkp-details to not issue spurious newlines for FPWs.

The additional newline seems to have accidentally been introduced in2c03216, in 9.5. The newline is only issued when an FPW ispresent for the block reference.While there could be an argument that removing the newlines in theback branches could cause a problem for somebody parsing thepg_waldump output, the likelihood of that seems small enough. It seemsat least equally likely that the randomness of when newlines areissued causes problems.Author: Andres FreundDiscussion:https://postgr.es/m/20191029233341.4gnyau7e5v2lh5sc@alap3.anarazel.deBackpatch: 9.5, like2c03216.
