separate_wider_position & names_sep

[hanguojun007]

Hi ,this is my example, i think it may be wrong.
when i set names_sep = "_" and cols_remove = FALSE，the x column become x_x.

df4 <- tibble(x = c("202215TX", "202122LACC", "202325"))
df4 |>
  separate_wider_position(
    x,
    widths = c(year = 4, age = 2, state = 2),
    names_sep = "_",
    too_few = "align_start",
    too_many = "drop",
    cols_remove = FALSE
  )

A tibble: 3 × 4

x_year x_age x_state x_x

1 2022 15 TX 202215TX
2 2021 22 LA 202122LACC
3 2023 25 NA 202325

I think this might the be the expected behavior. According to the docs for the names_sep argument, it is a "composed of the input column name followed by the separator followed by the new column name". So in this instance it is x (input column) + _ (separator) + x (new column name).
