strip blank line from examples in <pre>

[ratijas]

There is a special parsing rule for the <pre> tag itself which forces to
ignore the leading line breaks to be removed1. But it does not work on a
nested <code> tag.

I am sure there should be a better way to do it. Heck, I'm not even sure if this would be rendered correctly! But for now, pointing out a problem, and providing you with such PR is the best I can do.

@ratijas thank you for this :)

I tested it manually:

after:

Since my frontend knowledge is limited I would love to have another pair of eyes on this change.

Looks like an ok hack for now, it'd be nice if tera had some better way to do this.

Do you know any way to do this with tera? I think even the jinja2 trim_blocks and lstrip_blocks wouldn't help here, because it's about whitespace between HTML tags, and not jinja tags.

I checked if other template had the same problem and didn't find any other occurrences.

Also a quick search didn't find any nicer way of doing this with tera without too much complexity.

That's because pages are stored as half-rendered HTML. Wouldn't have been a problem with markdown + syntax highlighted triple-backtick code blocks.
