Add hash for block elements #10
Description
Migrated from RT originally by stas@sysd.org
Would be nice to have a list of elements which "break line" when textified. I actually this in my HTML::AsText::Fix:
# source: http://en.wikipedia.org/wiki/HTML_element#Block_elements
%isBlockElement = map {; $_ => 1 } qw(
p
h1 h2 h3 h4 h5 h6
dl dt dd
ol ul li
dir
address
blockquote
center
del
div
hr
ins
noscript script
pre
);
Not sure what to do with <br>: it breaks line but it's not a block element.

I think it would be useful to list all tags which affect the screen display AND are NOT flow/inline/phrasal. That is, one of their characteristics would be that they cause line breaks in most (if not all) cases. %isBlockElement is fine as a name, although for consistency with %isPhraseMarkup, perhaps it should be %isBlockMarkup?
There is still the question as to whether tags which put nothing directly on the screen (e.g., ) but might have children which do, should go into the %isBlockElement or %isPhraseMarkup, or get a new list: %isNonDisplayMarkup? Also, should %isBlockElement contain children which can only appear under another block element (e.g., thead, tbody, tfoot, tr, caption, etc. under table; or leave it as just table)? It's not clear how these lists are intended to be used. Presumably a given tag should appear only once in a "basic" list, and possibly again in composite lists.
Changes needed for %isBlockElement:
That should bring it up to date for HTML v4 (see also Github #5)
