Argh, this happens to me all the time: I type a comment like "@Jon can you please explain that part in more detail?" and it ends up as "can you please explain that part in more detail?". This makes me look like a fool that doesn't capitalise the first letter of sentences.
This was mentioned before:
Message's first letter stays lowercase when redundant @user is truncated
This feature won't go away and automatically capitalising my comment would not be a perfect solution either, so I am fine with this. I (grudgingly) accept that.
BUT!

What is this? There is no reason to have bad capitalisation on this one. Can this tiny little byte in the source code be fixed? Please? Pretty please? Please pretty please with sugar on top?
