Regression output is duplicated

[nilshg]

Running the readme example in the Julia REPL (1.11.2) I get:

julia> @regress log(MPG) log(Horsepower) log(Weight) log(Displacement) fe(Cylinders), robust
Kezdi.jl> @regress log(MPG) log(Horsepower) log(Weight) log(Displacement) fe(Cylinders), robust

May need to add ; to this line:

Kezdi.jl/src/functions.jl

Line 53 in 2ddd8ef

display_and_return(x) = (display(x); x)

[gergelyattilakiss]

This seems to be an issue with only multivariate regressions. This is because only that part is passed to display...

[korenmiklos]

If we want to change display behavior in REPL or outside, we can test for isinteractive() https://docs.julialang.org/en/v1/base/base/#Base.isinteractive

We intended to display all "side-effect" outputs to show than even in batch operation. This is just an omission that we forgot to call display_and_return.
