print.dplyr_step ignores `n`

[JosiahParry]

The print method of a tibble permits the user to supply a value n to determine the number of rows to be printed. When supplying n = 1 to ... the argument is silently ignored and not propagated to the tibble print method. n = 6 is hard coded into the print method:

dtplyr/R/step.R

Line 196 in 6e923bb

cat_line(format(as_tibble(dt, .name_repair = "minimal"), n = 6)[-1]) # Hack to remove "A tibble" line

library(dtplyr)

print(lazy_dt(iris), n = 1)
