These are salvaged from closed-PR #3216.

@esenapaj
I'm very glad about you, correcting my spelling.
Even more glad i'd be, if you had commented the matter. Are these function call really too late/early`?

If you think yes - let's talk about that and do it the right way, instead of correcting the spelling.

Fixing "to late/early" to "too late/early" was transacted by @thinkyhead.
I can't be determined whether those are really too late/early or not,
because PR #3082(also #2820, #2819) are difficult for me.

A lot of general code cleanup has come through lately with these kinds of tweaks to comments, adding GPL headers, etc. I wouldn't take it to have any other implications. However, these comments were interesting, so it seemed better not to remove them, since comments like these (which appear here and there in the code) indicate that some code is under scrutiny or not fully trusted. The authors of such comments might settle upon an answer and remove them later, so I always try to leave them in.
