I didn't consider that all newlines in the pre block will be printed and we
thus shouldn't wrap html that has it's tags on separate lines (i.e. contains
superfluous newlines) - wrapping in a div less accurately represents
org-html-export but it provides the same information and gives us more freedom
in the return value of HighlightCodeBlock as well as allowing us to keep the
html tags on new lines (consistency).
Org mode separates kvs not as initially assumed by whitespace (~ csv) but
rather at keywords (~ :\w+).
This is still not replicating Org mode behaviour though as I decided against
attributes ignoring multi-definitions. Instead we stack their
values (and those existing on the element) for certain attributes (class, style
for now).
e.g.
[[foo]]
would become <foo class="a"> in Org mode but becomes <foo class="a b"> with
go-org.
- was missing spaces between attributes when rendering to org
- was duplicating attributes when rendering to html - now we join / replace
attributes depending on the name - for now only class & style are appended
