Is there any way to preserve white space in code blocks?

I've created a bunch of code blocks in my help article with carefully formatted whitespace. When I save the article the whitespace is stripped. I'm talking specifically about whitespace to the left of content.

This:

" some-command"

Becomes:

some-command

I had to quote the first example because the help center does the same snipping...

When I edit the article the whitespace is back! How can I keep it in place for viewers of the article?
