I'd suggest firing empty for the reason that there may be some minor
spitting and flaking of brick/cement in the repaired area and some specks
may land on glazed ware. If the repaired area is down low, or can be
shielded fron the pieces being glazed, go for it.

I used some kiln cement to repair some brick damage in my electric kiln.
The
maintenance tells me to fire it to cone 5 empty the first time. I have a
load ready to glaze fire to cone 6 and wonder what risk I take by skipping
the empty fire and going ahead with the glaze fire.

Roger & Chuck:
the kiln cement I use says not to apply on the lid, but, my lid is cracking
big time & i've had to do it 2 times now....the cement I use says to wait 24
hrs before firing, nothing about firing empty 1st.
I'm worried about my lid! the cracking & all...it is an electric kiln
