Currently I can see no appropriate way of avoiding adding

block to any Textile code. Any text enclosed with \n is currently being put to the

tag.

In php textile it is possible to avoid this by adding a space character in the beginning of the line (see https://txstyle.org/doc/2/paragraphs):

a line beginning with a space will be left untouched, and not wrapped in

...

tags

One of the cases where the issue is important is when using the @

tag and this markup is usually wrong, because the included page is usually not a single paragraph, but contains some blocks, headers, etc itself.

Currently there is a bug (#13695) in currently used Redcloth3, which makes a workaround for the described issue. When you start the line with some other tag, the remaining text will not be enclosed in a paragraph:

@{{include(page)}}@

The same example can be used with the code tag instead of the pre tag which will also work this way.

This can be used as a workaround, but since Redmine is slowly moving to RedCloth4 developers must ensure that the new Textile formatter will support not enclosing text blocks into paragraphs. In a quick scan of RedCloth4 doc I can't find a way to do so. Syntax like in php textile can be used for that, where "no-paragraph" is a line started with a space character.
