Line info for first statement in short form function definitions is wrong

e.g.

for
https://github.com/JuliaLang/julia/blob/b076d04bf44f7e064a9875525c239471bd6e7563/base/broadcast.jl#L196-L197

It's not really the floor that is the problem but the current line. It should be at 197 but we get told that the statement is on line 196 so that is what we show, ref JuliaLang/julia#31458.
