More helpful error message on already existent page when listifying
Closed, ResolvedPublic

Description

When user tries to output listify to a page that already has content, pwb fails with

Page %s already exists, aborting.

Even though solution can be found in documentation, it would be easier for user to get a hint on how to solve this with adding something like

Page %s already exists, aborting. Use option -overwrite to overwrite the output page.
