indentation_linter disagrees with styler indentation

Possibly related to: https://github.com/r-lib/lintr/issues/2011#issuecomment-1661957104.

indentation_linter and styler do not agree in some cases using long column names inside a function.

Reprex dplyr

library(dplyr)

mtcars %>%
  rename(
    big_long_prefix_num_cylinders = cyl,
    big_long_prefix_horsepower = hp,
    big_long_prefix_weight = wt,
    big_long_prefix_automatic = am
  ) %>%
  mutate(
    big_long_column_name_that_cant_fit_in_col_limit =
      mpg == (big_long_prefix_num_cylinders * big_long_prefix_horsepower) &
        (big_long_prefix_weight * big_long_prefix_automatic) # styler formats to this
  )

This configuration results in the lintr error:

[indentation_linter] Indentation should be 6 spaces but is 8 spaces.

In other words, lintr wants the format below, which styler will auto-fix:

  mutate(
    big_long_column_name_that_cant_fit_in_col_limit =
      mpg == (big_long_prefix_num_cylinders * big_long_prefix_horsepower) &
      (big_long_prefix_weight * big_long_prefix_automatic) # lintr wants this
  )

Reprex data.table

Here's another example using data.table:

library(data.table)
library(dplyr)

mtcars2 <- mtcars %>%
  rename(
    big_long_prefix_num_cylinders = cyl,
    big_long_prefix_horsepower = hp,
    big_long_prefix_weight = wt,
    big_long_prefix_automatic = am
  )

mtcars2[, big_long_column_name_that_cant_fit_in_col_limit :=
  round(big_long_prefix_num_cylinders - big_long_prefix_horsepower, 2)] # styler wants this

lintr throws an error:

[indentation_linter] Indentation should be 9 spaces but is 2 spaces.

lintr wants this format, which styler will auto-fix:

mtcars[, big_long_column_name_that_cant_fit_in_col_limit :=
    round(big_long_prefix_num_cylinders - big_long_prefix_horsepower, 2)
]

FWIW, here is what both {lintr} and {styler} can agree to:

library(dplyr)

mtcars %>%
  rename(
    big_long_prefix_num_cylinders = cyl,
    big_long_prefix_horsepower = hp,
    big_long_prefix_weight = wt,
    big_long_prefix_automatic = am
  ) %>%
  mutate(
    big_long_column_name_that_cant_fit_in_col_limit = {
      mpg == (big_long_prefix_num_cylinders * big_long_prefix_horsepower) &
        (big_long_prefix_weight * big_long_prefix_automatic)
    }
  )

mtcars[
  ,
  big_long_column_name_that_cant_fit_in_col_limit :=
    round(big_long_prefix_num_cylinders - big_long_prefix_horsepower, 2)
]

Just wanted to say thanks for looking into these consistency issues, very important work! Just ran into the inconsistencies and for now need to disable the indentation linter to avoid too much work ...
