65016cdca4 Fix superscript and subscript support 
Introduce html_subscript_close callback. Draw opening and closing brackets
and carets for subscript and superscript text directly in the element
handlers rather than performing weirdness in the renderer. This both
improves readability and fixes bug 284, misplaced brackets with subscripts.

6947902b57 Replace special handling in end_element with callbacks 
Add close callbacks html_html_close, html_style_close, and
html_xmp_close. end_element now calls the element close callback instead
of performing special handling for certain tags.

d19dcaa3e7 IMHO line_break should fill lines with spaces. This is done for <pre>.

3ce3f01f30 Add support for forcing wrapping at the screen boundary 
This patch modifies ELinks wrapping behavior slightly.

 * The wrap command now toggles line wrapping in HTML mode, as well as
   text mode.  Note that when the HTML view of a page is wrapped, its
   source view is unwrapped, and vice versa.
 * Tabs in text-mode lines are now handled correctly.
 * Wrapping a line that reaches exactly to the edge of the screen will
   no longer produce a blank line in text mode.
 * Text within extra-wide table cells is now wrapped to less than the
   screen width, to eliminate sideways scrolling.

The last point is only enabled by setting TABLE_LINE_PADDING to a
non-negative number, in the src/setup.h header file, because it is a
significant change of behavior from previous versions.

a4831fef2d Make it easier to work with DOM stack contexts outside of the callbacks 
The problem is to get access to the context when it is not the first one
and it has to happen outside of the context callbacks. This changes the
memory management so that the context adder returns the context. To further
improve the use of contexts add a context destructor which makes it
possible to unregister (temporary) contexts.

c4a1031b2e Move code for the final source highlight flushing to document pop callback 
This requires the document root stack state is made mutable and is popped.
Should make render_dom_document() more generalised. For SGML_PARSER_STREAM
this has the fun property that the stack will magically free the root node.

 - dom_select_pop_element(): Use stack->contexts since it is the
   select_data stack and it owns the first context
