Regex to match all trailing whitespace _and_ newlines.

[Dotan Cohen]

In the terrific Anki [1] application I am trying to remove trailing
whitespace from form fields. This is my regex:
[\n+\s+]$

Actually, even simplifying it to [\n] or [\r\n] is not matching any
newlines! What might be the cause of this? Note that I am not entering
the regex in Python code, I am entering it in a regex-supporting
Find/Replace dialogue in Anki. Anki is written in Python.

Thanks.

Hi Peter, sorry for the _late_ reply.

It turns out that Anki stores newlines internally as <br>, since its
display model is based on HTML. Thanks, though!
