ignore min/max variables when detecting orientation in geom_bar

[thomasp85]

Fixes #3866

The check for range_is_orthogonal in geom_bar() was unneeded and resulted in failure with edge cases

Looks good, but could you fix the document as well?

ggplot2/R/utilities.r

Lines 456 to 461 in bb86d33

	#' - `range_is_orthogonal`: This argument controls whether the existance of
	#' range-like aesthetics (e.g. `xmin` and `xmax`) represents the main or
	#' secondary axis. If `TRUE` then the range is given for the secondary axis as
	#' seen in e.g. [geom_ribbon()] and [geom_linerange()]. `FALSE` is less
	#' prevalent but can be seen in [geom_bar()] where it may encode the span of
	#' each bar.

I mean I just want you to remove this sentence since geom_bar() no longer uses this option after this PR gets merged.

@thomasp85 May I tweak the document and merge this?

[thomasp85]

Yes — sure. I’ve been elsewhere for a while

[yutannihilation]

Sure.
