include.lowest missing in function arguments of cut_interval et.al.

[dpprdan]

The documentation for cut_interval reads

...   other arguments passed on to base::cut

One of the arguments of base::cut is include.lowest, but using it with cut_interval/cut_number/cut_width results in an error.

table(ggplot2::cut_interval(runif(1000), 10, include.lowest = FALSE))
#> Error in cut.default(x, breaks(x, "width", n, length), include.lowest = TRUE, :  formal argument "include.lowest" matched by multiple actual arguments

So either include.lowest = TRUE should be included in the main function arguments of cut_interval et.al., e.g. cut_number(x, n = NULL, include.lowest = TRUE, ...) This is to be preferred IMHO since it makes it's use transparent. Or the documentation should be transparent about include.lowest not being allowed.

BTW: Shouldn't these functions rather be part of scales, since both these functions and scales are about transforming variables?
