Description

Wiki diff page generates the following HTML:

<div class="text-diff">
...
<br />         sleep 10 
<br />       end 
...
</div>

From: http://www.redmine.org/projects/redmine/wiki/HowTo_run_Redmine_as_a_Windows_service_%28win32-service_+_taskill_approach%29/diff?version=3&version_from=2&commit=View+differences

And here is div.text-diff style:

.text-diff {
padding: 1em;
background-color:#f6f6f6;
color:#505050;
border: 1px solid #e4e4e4;
}

From: source:tags/2.0.3/public/stylesheets/application.css#L777

Spaces in Wiki page are ignored because the HTML doesn't use <pre> tag and the CSS also doesn't use white-space: pre.

Here is a patch that removes simple_format_without_paragraph and surrounds @diff.to_html with <pre class="text-diff"> instead of <div class="text-diff">.

I think it would be better to add white-space: pre-wrap; to text-diff class.

diff --git a/public/stylesheets/application.css b/public/stylesheets/application.css

Please see the following screenshots. Without white-space: pre-wrap;, you cannot see the whole content of long lines.
