// - If a single clip should be pasted, and it should be pasted inside another
// clip, no new clips are generated. The audio is simply inserted.
// This resembles the old (pre-multiclip support) behaviour. However, if
// the clip is pasted outside of any clip, a new clip is generated. This is
// the only behaviour which is different to what was done before, but it
// shouldn't confuse users too much.
//
// - If multiple clips should be pasted, these are always pasted as single
// clips, and the current clip is splitted, when necessary. This may seem
// strange at first, but it probably is better than trying to auto-merge
// anything. The user can still merge the clips by hand (which should be
