Title: More verbose error on duplicate post title

I was stumped by the "file already exists" error message until I
realized it was a backup copy of my file leading to duplicate post
entries. This is a more verbose error message hinting towards that
as a potential error.

This merge request is the updated version with the wording you have proposed.
