You only used one space in this comment ;)

I wonder if that gets changed by the site or something. I remember thinking "I better be sure to use two spaces otherwise someone will call me out on it."

Here's a test. I definitely put two spaces prior to this sentence.

EDIT - indeed it seems that HN changes the spacing.
