[MC-58537] Supplemental selectors in /scoreboard teams join & leave don't work with the @e selector

/scoreboard teams add blah

works: /scoreboard teams join blah @p @p @p @p
works: /scoreboard teams join blah @e @p @p @p
doesn't work: /scoreboard teams join blah @e @e @e @e

supplemental selectors weren't setup to work with the @e selector

Environment

Windows 7 Professional SP1 64-bit
Java Version 8 Update 5 (build 1.8.0_05-b13)

what do the last 3 selectors do, because when I get the help message it says:

/scoreboard teams join <team> [player]

and not

/scoreboard teams join <team> [player] [player] [player] [player]

They're just more selectors you can add at the end. Try it, it'll work.

/scoreboard teams join <team> [player]
/scoreboard teams leave <team> [player]

These are the only commands that have this ability that I know of.

so like you can add the closes and a random player with:
/scoreboard teams join <team> @p @r
?

yup
