Buildifier removes some comments

[pmbethe09]

[ # This line will be eaten by buildifier
# but not this line.
cc_binary(
name = "something_%s_useful" % lang,
)
for lang in li]

I'm working on this right now. Actually slight correction, there needs to be an input like

[a for b in c
]

[ #comment on the first line of a container with the opening [ or ( or { will be eaten
]

for the bug to materialize

Currently buildifier doesn't allow to make comment on a multiline list, for example:

items = [
    a,
    b,
]  # a list of items

also it doesn't allow commenting on a function call:

foo(
  x,
  y,
)  # bar

I'm working on this issue and I'd like to remove these restrictions as they seem to be related to the initial problem. Are there any objections / reasons why buildifier is implemented this way?

Another example of a missing comment:

[
  x
  for x in y #foo
  if x # bar
]

is formatted to

[
  x
  for x in y
  if x
]

due to a bug in the printer.
