Nit: Extra blank lines (3 places)

[Steve McKay, 2012/06/11 22:09:38]

Done. Though allow me to proselytize for more whitespace a bit. An empty line
after a line wrap makes it easier to distinguish content from the wrapped
content preceding it, especially so in the middle of a block.

[Peter Kasting, 2012/06/12 00:31:37]

I don't mind whitespace in general, but a blank line at the beginning of a
function is something I've never seen elsewhere in Chrome code.

[Steve McKay, 2012/06/14 22:06:23]

Done.

Is this supposed to be uncommented? I see that WebIntentsRegistryFactory exists.

[Steve McKay, 2012/06/11 22:09:38]

Trying to segregate CLs to keep the switch to PKS separate from integration with
WebIntentsRegistry. I can remove if this is offensive, but otherwise like it
here for later uncommenting.

[Peter Kasting, 2012/06/12 00:31:37]

Do you mean that right now the ProtocolHandlerRegistry doesn't actually depend
on the WebIntentsRegistry at all?  If so this line should probably be entirely
absent.

[Steve McKay, 2012/06/14 22:06:23]

Done.

Nit: Could put on previous line

This is already the default behavior.

Done.
