如何在Eclipse PDT中重新格式化多行注释？

在Eclipse PDT,Ctrl-Shift-F重新格式化代码.但是,它根本不会修改注释.有没有办法将不规则的多行注释重新格式化为每行80个字符(或其他)？

即转换

// We took a breezy excursion and 
// gathered Jonquils from the river slopes.  Sweet Marjoram grew 
// in luxuriant 
// profusion by the window that overlooked the Aztec city.

至

// We took a breezy excursion and gathered Jonquils 
// from the river slopes.  Sweet Marjoram grew in 
// luxuriant profusion by the window that overlooked 
// the Aztec city.

(我认为这也适用于常规Eclipse.)

更新原来Eclipse在Java模式下将重新格式化上面的行,但前提是它们是/**/ - 样式的注释.它会缩短//太长的行,但它不会连接太短的行.
