Bug Description

To replicate:

1. Go to your user account settings and turn the HTML editor off
2. Set the forum post delay to 0 minutes (to make testing quicker)
3. Make a forum post that runs across multiple newlines.
4. Look in your Inbox, and look at the email you receive

Expected result: You should see one newline in the message for each newline in the original post
Actual result: You'll see two newlines in the message for each one in the original post.

This does not seem to happen when the HTML editor (TinyMCE) is active. Possibly TinyMCE strips out the newlines from the text before saving it.

Diagnosis so far (going home for the day now):

Text comes in as "Test\r\nTest"
Mahara/lib/web.php::format_whitespace (line 3165) changes this to Test<br>\nTest
Mahara/interaction/forum/lib.php:ActivityTypeInteractionForumNewPost->__construct (Line 939) then does

$post->textbody = trim(html2text($post->body));

giving the two "\n"s.

So it looks like format_whitespace needs to just put <br> or just \n... will see tomorrow, Lord willing.

The attached patch deals with the issue as reported.

That said, turning back on the HTML editor, I've noted that it suffers from the same problem but for an entirely different reason. Given

<p>this is a reply</p>
<p>this is a second line of a reply</p>

html2text returns

this is a reply

this is a second line of a reply

So then, should this bug have its scope extended?

Hi Nigel,

Now that you are using Gerrit, can you please put your patch there? :-)
