According to the HTML 4.01 Specification
http://www.w3.org/TR/html401/appendix/notes.html#notes-line-breaks
"a line break immediately following a start tag must be ignored" and "this applies to all HTML elements without exception".
But when an inline-level element is given the CSS properties { display: block; white-space: pre }, the linebreak immediately following the start tag is not ignored.
Reproducible: Always
Steps to Reproduce:
Consider the following html document
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/HTML4.01/strict.dtd">
<html><head><style type="text/css">
span { display: block; white-space: pre }
</style></head><body>
<p>first line
<span>
second line
</span>
third line</p>
</body></html>
Actual Results:
The actual results are
first line
second line
third line
Expected Results:
The expected results are
first line
second line
third line

This bug appears to be unrelated to the { display: block } property. It occurs when ANY block-level element EXCEPT <pre> is given then { white-space: pre } property. For example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/HTML4.01/strict.dtd">
<html><head><style type="text/css">
div { white-space: pre }
</style></head><body>
<p>first line</p>
<div>
second line
</div>
<p>third line</p>
</body></html>

Summary: extra linebreak when { display: block } is combined with { white-space: pre } → extra linebreak when block-level element has { white-space: pre }

Actually, this bug affects ANY ELEMENT that has { white-space: pre } except for <pre>. It is not specific to block-level elements. Given what the HTML 4.01 Specification says about linebreaks, the following two documents should be rendered the same. Unfortunately, they aren't.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/HTML4.01/strict.dtd">
<html><head><style type="text/css">
span { white-space: pre }
</style></head><body>
<p>This
<span>
should be
</span>
all on one line.</p>
</body></html>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/HTML4.01/strict.dtd">
<html><head><style type="text/css">
span { white-space: pre }
</style></head><body>
<p>This <span>should be</span> all on one line.</p>
</body></html>
Summary: extra linebreak when block-level element has { white-space: pre } → extra linebreak with { white-space: pre }

Parsing that way is actually not compatible with web content. HTML5 is going to specify parsing that is.
In any case, this is not a style system issue.
