Triple aggressive moves binary operator from beginning of line into comment at end of previous line

[eli-b]

Using --aggressive --aggressive --aggressive, this:

x = (
    1111111111111111111111111111111111111111111111111111  # C1
    and 1111111111111111111111111111111111111111111111111111  # C2
    and 1111111111111111111111111111111111111111111111111111  # C3
)

is turned into this (bug):

x = (
    1111111111111111111111111111111111111111111111111111  # C1 and
    1111111111111111111111111111111111111111111111111111  # C2 and
    1111111111111111111111111111111111111111111111111111  # C3
)

Using --aggressive --aggressive doesn't reproduce this error.

I think this may have been introduced in commit 0d28a5b.
