Now it doesn=92t, as we have the U+0020 SPACE, the U+00A0 > NON-BREAKING SPACE, and the U+2009/U+200A THIN SPACE and HAIR SPACE= , > respectively, as well as other fixed-width spaces. But in the real world, there's still a lot of text with 2 spaces between sentences, and Emacs needs to DTRT with that. An editor cannot throw in the towel when it bumps into text that uses two spaces.
