Can panic-recover handling add to the function Group.Go()?

When the program is processed in multiple goroutines, panic may occur, which will cause main goroutine to crash directly. Can following logic add to Group.Go() ?

```diff
// Go calls the given function in a new goroutine.
//
// If the function returns an error it is added to the group multierror which
// is returned by Wait.
func (g *Group) Go(f func() error) {
g.wg.Add(1)

go func() {
defer g.wg.Done()

+ defer func() {
+ if r := recover(); r != nil {
+ g.mutex.Lock()
+ g.err = Append(g.err, fmt.Errorf("%v", r))
+ g.mutex.Unlock()
+ }
+ }()

if err := f(); err != nil {
g.mutex.Lock()
g.err = Append(g.err, err)
g.mutex.Unlock()
}
}()
}
```
