How can I force MediaWiki to respect single line breaks?

问题

By default, MediaWiki ignores single line breaks, treating them as a single space. To insert a new line in a page, you must insert two consecutive line breaks in the source, which results in a new paragraph: </p><p>. It's also possible to insert <br /> directly into the source.

How can I modify the MediaWiki parsing engine so single line breaks in the source are replaced automatically with a <br /> in the resulting HTML?

Use https://www.mediawiki.org/wiki/Extension:Poem

<poem>
Roses are red
Violets are blue
</poem>

You could write an extension that adds br tags to newlines when parsing the wikicode. However, you'd have to be very careful - you don't want every newline in the wikicode to actually be a br tag, do you?

Edit: you don't want every newline to be a br tag, because not every newline in the wikicode should actually be a linebreak. For example, a table:

{|
|+ The table's caption
|-
|Cell 1
|Cell 2
|-
|Cell A
|Cell B
|}

It would turn quite messy if you added br tags into the table code.

This html tag seems to do the job for me.
