Did you mean "buttons" in plural?
Use full comment sentences: // The released buttons.

Use "!=" for bitmask operations. A ">" looks like an ordered operation.

This doesn't seem quite right. Did you mean
// Buttons specify the set of buttons to track. The zero value is equivalent to the
// primary button, not the empty set.
?
Ah, I see from the rest of your change that I wasn't clear enough in my description. What I meant by the Buttons field is that it should be set by the user from Click, not Click itself. The purpose of (the zero value of) Buttons is maintain the old behaviour where only the primary mouse button would be tracked. Users such as yourself that need to track other buttons can include them in Buttons.

Should this change to something like
// pressed tracks whether one or more buttons from the Buttons set is pressed.
?

"primary mouse button". Sorry for renaming the buttons while you're working on this change :)

Click shouldn't update its Buttons field. See my comment on the field above.
