Support for XEP-0393 preformatted text

[poVoq]

It would be nice if Movim would support preformatted text as by XEP-0393 with the three back ticks.

Gajim for example supports this and you see this being used relatively often in developer discussions.

I think this could be styled similar to the /code command that is already available, see: #408

Thanks!

This ticket can easily be done by a contributor :)

I would be interested in this feature. I prefer reStructuredText & Asciidoc (& even Djot) to Markdown due to all of its limitations & lack of features & this would mean I could provide my own HTML.

That's not really the purpose of XEP-0393 though. It is rather for Markdown like code-blocks.

What you want is the (deprechiated) XEP-0071 I think, and there are several people who would like this to be revived.

XEP-0071: XHTML-IM is not happening

I'm ok to complete the XEP-0393 support.
I added the "easy-first-ticket" tag for those that would like to do it, it should be pretty simple
