- update to version 7.8:
* textwrap.c, langinfo.c, hxnormalize.c: Added knowledge about
languages that do not use spaces between words. In such languages,
a newline should not be converted to a space in outc() in
textwrap.c, but only to a break opportunity.
* hxtoc.c: The element to group headings in HTML5 is called
HGROUP, not HEADER. The heading of a section (SECTION, ARTICLE,
etc.) need not be the first element, there may be non-header
elements before it.
* hxwls.c: Print "longdesc", "classid" or "codebase" in the second
column for the corresponding attribute. Also recognize srcset
(somewhat).
* hxnormalize.c: Added option -X to indicate the input is XML
instead of HTML. Handle conversion of CDATA elements to XML by
escaping < and & instead of adding
