Language function textformat
{textformat} 是一个用于格式化文本的块函数。它主要清理空格和特殊字符，并通过在边界处换行和缩进行来格式化段落。
您可以显式设置参数，也可以使用预设样式。目前，"email" 是唯一可用的样式。
属性

| indent | 0 | 每行缩进的字符数 |
| indent_first | 0 | 第一行缩进的字符数 |
| indent_char | (单个空格) | 用于缩进的字符（或字符串） |
| wrap | 80 | 每行包含的字符数 |
| wrap_char | \n | 用于换行的字符（或字符串） |
| wrap_cut | FALSE | 如果为 TRUE，则 wrap 会在确切的字符处换行，而不是在单词边界处换行 |
