What do you think about this modifications?

Hi,

I've modified your css and spoiler.module a little bit. What do you think about it? Perhaps it looks a little bit better than just chaning text and background collor.

in spoiler.module I changed the function _spoiler_filter_process with:
return preg_replace('#\[\s*spoiler\s*\](.*?)\[\s*/\s*spoiler\s*\]#is', t('<a href="#" class="spoiler">Spoiler: <span>$1</span></a>'), $text);

and in spoiler.css I replaced the whole content with:

a.spoiler, a.spoiler:visited, a.spoiler:active, a.spoiler:hover {color:#000; background:#fff; border: 1px dotted #ccc; text-decoration:none;}
a.spoiler span {display:none;}
a.spoiler:hover {border: 1px dotted #cccccc;}
a.spoiler:hover span {display:inline; font-weight:normal;}
