AFAICT, the problem at hand is about frame-focus-changes, not about
window-focus-changes (Nick's message said "I might just want to select that
window to resize it" suggesting pretty clearly that he's talking about
frames rather than windows).

No, I'm not confusing them, I was talking about frames (and never mentioned
the word "window"), tho I didn't make it explicit since I thought the
context was sufficiently clear.

BTW, in a click-to-focus environment (I'm still talking only about frames's
focus), I think it'd indeed also make sense (as Nick's message mentioned) to
ignore a click on a sensitive mode-line element if it was used to get focus.

Basically, any non-trivially-safe (point movement and window selection is
safe, most of the rest isn't) operation should not be triggered by
a click-to-focus.

Maybe the mouse-face should also be inactive on frames that don't
have focus.
