[PATCH v3 1/6] completion: add comment for test_completion()

[Felipe Contreras <felipe.contreras@gmail.com>]

So that it's easier to understand what it does.

Also, make sure we pass only the first argument for completion.
Shouldn't cause any functional changes because run_completion only
checks $1.
