I'm personally a fan of using two spaces after periods, in order to improve readability of my material. But lately I've been using the Quick Draft feature in the dashboard, to jot things down, and then I edit them later into final posts.
I've noticed in every case, that when I save a post created this way, all my careful double spaces are converted to single spaces. This does not happen if I use the standard New Post feature. Only when created from a Quick Draft.
This appears to happen for comments too. Any comment (or comment reply) left that uses two spaces after periods, will be converted to single spaces upon saving. The spaces are actually modified in the comment source.
Anyone know why this is and if it's a bug?
