feature request: removing empty lines in function argument specifications

[IndrajeetPatil]

Feel free to close this if you feel the gain here is inconsequential for the work needed to support this feature, but I was expecting the following code

styler::style_text(
  "foo <- function(
                  a,
                  b = 2,
                  c = 3,
                  d = 4) {
    print('hi')
  }"
)
#> foo <- function(
#>                 a,
#>                 b = 2,
#>                 c = 3,
#>                 d = 4) {
#>   print("hi")
#> }

^{Created on 2021-01-20 by the reprex package (v0.3.0.9001)}

to be styled as-

foo <- function(a,
                b = 2,
                c = 3,
                d = 4) {
  print("hi")
}

I couldn't find relevant discussion about this in the tidyverse style guide, but does that make sense to you?

Makes complete sense. Actually kind of a duplicate of #549, but not covered in the associated PR (although specifically mentioned as an example).
