This is indeed confusing and I have been meaning to do something about this
for a while now (yet another item in my todo list...). Keep in mind that
there is actually no discrepancy. The marker is turned onto its side. So
the marker edge width parameter actually effects the cap's thickness. So,
having a finite capsize, but a zero thickness should result in no cap being
drawn.
But it is totally unintuitive that mew should have anything to do with the
cap thickness and what should be done is introduce a new kwarg "capthick"
or "capheight" and eventually have it completely replace the responsibility
of mew in errorbars.
