Add legend to plot with only 1 curve

[SandervandenOord]

Currently it is not possible to add a legend to a plot with only 1 curve. It would be nice if you could do that.

At the moment there's only a workaround such as creating an overlay with the same curve:

curve1 = hv.Curve([3, 4, 5], name='just one line')
curve1 * curve1

Would be nice if adding a legend to a plot would be more intuitive.
