The CSS file https://bugzilla.wikimedia.org/skins/custom/vector.css used in the new styling of Wikimedia's Bugzilla contains the following rule:

pre {

	padding: 1em;
	border: 1px dashed #2f6fab;
	color: black;
	background-color: #f9f9f9;
	line-height: 1.1em;

}

The padding, border and background defined in this rule make diffs really ugly and hard to read, since Bugzilla wraps each diff line in a separate pre element. This rule should either be removed or overridden by a more specific one.
