merge: improve documentation of fbid dict used for merge bid

I improved the comments explaning what the dict contains meanwhile organizing
the comment structure which prevents some confusion.

Due to formatting issues, the empty dict was wrapped in `()` which might decieve
in thinking that it's a tuple of dict until you decide to find a comma.
