Btw, the keymap property we put on the header-line does bind mouse-2
to a command that follows link, not mouse-1:

    (define-key keymap [header-line down-mouse-1] 'mouse-drag-header-line)
    (define-key keymap [header-line mouse-1] 'mouse-select-window)
    (define-key keymap [header-line mouse-2] 'Info-mouse-follow-link)
    (define-key keymap [mouse-2] 'Info-mouse-follow-link)
    (define-key keymap [follow-link] 'mouse-face)

So I guess this is somehow related to the processing of
mouse-1-click-follows-link.
