Subject: [PATCH] Trim user input from prompts where appropriate (#1854)

* Trim user input from prompts where appropriate

* Run formatter

* Use "page title" language instead of "page name" in notifications.

Existing language in prompt asks for a "page title".

* Use const for prefix inputs as they are never trimmed
