Preformatted inline code

[martincizek]

Currently, inline code spans (i.e. <code> outside of a wrapping <pre>) are always subject to:

1. HTML whitespace collapsing in collapse-whitespace.js,
2. trimming in turndown.js and
3. flanking whitespace outplacement determined by node.js.

So it shares the very same behavior with emphasis and strong emphasis elements, for which the flanking delimiter run is defined by the spec. → Points 2 and 3 are not necessary.

And ref point 1: GitLab, a major implementor of the CommontMark format nowadays, has <code> element styled as white-space: pre-wrap;, which actually makes sense.

See the snapshots below. The lacking feature is that Turndown cannot produce such Markdown now.
