Previously the HTML writer was exceptional in not being
sensitive to the `--wrap` option. With this change `--wrap`
now works for HTML. The default (as with other formats) is
automatic wrapping to 72 columns.
A new internal module, T.P.Writers.Blaze, exports `layoutMarkup`.
This converts a blaze Html structure into a doclayout Doc Text.
In addition, we now add a line break between an `img` tag
and the associated `figcaption`.
Note: Output is never wrapped in `writeHtmlStringForEPUB`.
This accords with previous behavior since previously the HTML
writer was insensitive to `--wrap` settings. There's no real
need to wrap HTML inside a zipped container.
Note that the contents of script, textarea, and pre tags are
always laid out with the `flush` combinator, so that unwanted
spaces won't be introduced if these occur in an indented context
in a template.
Closes#7764.
- Add manual entry for (non-default) extension
`rebase_relative_paths`.
- Add constructor `Ext_rebase_relative_paths` to `Extensions`
in Text.Pandoc.Extensions [API change]. When enabled, this
extension rewrites relative image and link paths by prepending
the (relative) directory of the containing file.
- Make Markdown reader sensitive to the new extension.
- Add tests for #3752.
Closes#3752.
NB. currently the extension applies to markdown and associated
readers but not commonmark/gfm.
