This previously gave

This PR makes the all rows always use the "top right/bottom left" behavior. Because hist(histtype="bar") (the default) simply calls bar(), this PR also makes the behavior of hist() more consistent.

The deleted tests arehttps://github.com/matplotlib/matplotlib/blob/v3.1.0/lib/matplotlib/tests/baseline_images/test_axes/hist_steplog.png, which is now

(the lower margin is much more reasonable IMO) and#4608 (now both histograms go to 1e-2 -- one because that's what's passed as bottom, the other one because it goes basically to minus infinity but relies on the other's sticky margin).

Closes#4621 (which is essentially the same as the issue demo'ed above).
Closes#14981.

Make logscale bar/hist autolimits more consistents.

c1ea241

The bottom limit of log-scaled bar/hist plots now defaults to applyingnormal margins (possibly with null limits expansion) to the data limits,rather than being hardcoded to 1/log_base.  See changelog.Delete two tests that asserted that the lower limit was at 1/log_base.
