Comments by multi-byte characters are ignored

[a-suenami]

Hi, everyone. So thank you for great product.

I occurred in trouble and want to hear everyone's opinion.

I'm Japanese developer so often add some comment for each database column in Japanese.

For example:

create_table "users", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci", comment: "ユーザ", force: :cascade do |t|
  t.string "name", null: false, comment: "名前"
  t.string "email", null: false, comment: "メールアドレス"
end

However, they're ignored because they don't match a regular expression which checks diff between old schema and new schema, It's specified here.

If we don't have any problems, I want to fix the problem as follows.

# current
column_pattern = /^#[\t ]+[\w\*\.`]+[\t ]+.+$/

# I expect
column_pattern = /^#[\t ]+[^\t ]+[\t ]+.+$/

What do you think?

This still happens on HEAD of develop branch (i.e. 5d01c41), so we've switched to with_comment_column style instead of with_comment. It works great even if a comment includes any cause character like multi-byte characters. I hope this will help you.
