Patch v1.0 add Firefox compatible duplicateTabIn()

At a quick glance, you could use aTab || getBrowser().selectedTab instead.

Surely if aHistoryIndex is null then delta should be zero?

Yeah that's what I assumed at first too, but I couldn't match Firefox observed behaviour that way. Unfortunately I have to be compatible with their brain damaged implementation, so this silly construct.

Sigh. Brain fade at 2am. Cut and pasted the wrong block into my active patch.
Fixed.

Nit: fits in 80 characters without wrapping.

[duplicateTabIn(null, where) would have been nice, but not required for r+]

But you do realize that you can file bugs on Firefox code, don't you?

Oops. Apologies for this rude comment.

I think I've done that before, but not recently.
