What does "*display: inline" mean?
That one is an old browser hack. Since this revision is just a revert I did not investigate that much.
Any way, thanks to blame and revision history it is an undocumented browser hack added by simetrical in r77411. Roan had the confirmation when attempting to remove the hack in r78158.
Wish we could get it documented though.
Can you add /* a comment */ about it? :)
On further inspection of r93581. I suspect it is a browser hack for Internet Explorer. Maybe:
*display: inline; ^
Is equivalent to:
display: inline !ie; ^^^
That was part of r93581 change.
w:CSS filter#Star hack
It's for IE 7 and earlier.
