toggle misbehaving

[minusf]

Toggle does not work correctly in certain cases (python example):

d=(
    # "test1",
    "test2",
)

Now i would like to toggle the commenting to be like this:

d=(
    "test1",
    # "test2",
)

So i go into visual line mode and select both lines and press gcc. the result is:

d=(
    # # "test1",
    # "test2",
)

I can't decide to label this as "bug" or "enhancement".
Because it makes some users confused to make this behavior default.
I think it should have option to change multiline comment behavior.
