Vim：重新格式化和重新评论的自动化方式？

# book_id - integer
# chapter_id - integer (Optional)
# relative_url - Text: the url of the screencast file on S3,relative to the book's url
# view_count - integer

我安装了Tabular.vim,这让我走得很远：

# book_id      - integer
# chapter_id   - integer (Optional)
# relative_url - Text: the url of the screencast file on S3,relative to the book's url
# view_count   - integer

我想要一些自动生成这样的代码的方法.也就是说,包裹到79个字符,如果从前一个注释继续一行,则缩进.我得到的是这个：

# book_id      - integer
# chapter_id   - integer (Optional)
# relative_url - Text: the url of the screencast file on S3,relative to the
# book's url
# view_count   - integer

我正在寻找的是：

# book_id      - integer
# chapter_id   - integer (Optional)
# relative_url - Text: the url of the screencast file on S3,relative to the
#                book's url
# view_count   - integer

是否可以在现有的插件或热键序列中执行此操作？我知道gq,它会将文本重新格式化为在vim中设置的字符宽度,但它不会在注释等内容中添加缩进.
