I used to use CSE:, but have now switched to using [CSE] because that seems to be the prevailing convention (and is somewhat more visually distinctive). I think it makes sense to codify that convention, but not to require them. Sometimes, there is nothing appropriate to use. Sometimes, the first or second word of the commit message is naturally the same as what the title tag would be, and so including the title tag seems redundant.

I agree. I think the important part is that the name appear in an obvious context. That way, if I search my Inbox for the name, the relevant commit will appear, and it will be obvious why without reading a lot of text.
