[ignoreWhitespace] are newlines equal to spaces?

I'd like to use html-differ to write a test system for marked, where generated html output is to be compared to pre-written html code, to determine if the two are equivalent, so I would like to ignore whitespace differences, when they are not meaningful (as in <p> tags), but I noticed that newlines are treated differently than spaces:

<p>A link. Not anymore.</p>

is not considered equal to

<p>A link.
Not anymore.</p>

when, IMO, they should be.

I've tracked this to be probably determined by this line of code (line 39 on the right).

I'm aware this issue is related to CSS, and not HTML itself. According to CSS specification, when the white-space property is not pre, pre-wrap, or pre-line, segment breaks (i.e. newlines) are usually converted to a space U+0020.

Empieza por el código referenciado en el pull request #66, especialmente por la línea 39 de la derecha, y reproduce los dos ejemplos de HTML del issue. Comprueba cómo se comparan los nodos de texto de saltos de línea y espacios; el trabajo estará terminado cuando los ejemplos se traten como equivalentes sin cambiar los espacios en blanco que CSS conserva.
