legend_label doesn't work when plotting multiple functions at the same time

[jasongrout]

This gives a legend:

plot(x,legend_label='test')+plot(x^2,legend_label='test')

but this doesn't:

plot([x,x^2], legend_label='test')

Patch attached. Note that this depends upon trac_12960-fix_legend.2.patch, not for the fix itself, but for the doctest.

Looking at this. Doug - note that it's best to use the #12960 syntax so one can click on the hyperlink created.

I'm adding a doctest for people to see this as well in the live documentation.

Why the extra blank lines?

Also, note that even this didn't work before.

sage: q1 = plot([sin(x)], legend_label='trig'); q1

which I assume why you did the test you did.

Reviewer patch coming up.

This conflicts with #11998.

Am I the only one who finds it funny that a patch described as "be less aggressive about pruning legend labels" conflicts with a patch called "be more aggressive about pruning legend labels"?

I'll try letting #10514 take priority and modify #11998 to deal with it.
