5028 captures carried out so far will ALREADY have a write source
5029 named "Foo-N+1.mid" waiting to be used for the next capture.
5031 If we call new_midi_source_name() we will get "Foo-N+2". But
5032 there is no region corresponding to "Foo-N+1", so when
5033 "Foo-N+2" appears in the track, the gap presents the user
5034 with odd behaviour - why did it skip past Foo-N+1?
5036 We could explain this to the user in some odd way, but
5037 instead we rename "Foo-N+1.mid" as "Foo-N+2.mid", and then
5040 If that attempted rename fails, we get "Foo-N+2.mid" anyway.
