There is one issue that needs special attention, namely how to encode
such slur 'stubs' in input files. If there are two notes or more
under a slur, the input is rather straightforward; we can say, for
example,
```
c2\tweak to-right-barline ##t ( c2)
```
However, there is a special case as shown in the attached image, with
only a single note under the slur. My preferred solution would be to
start and stop the slur at the same note:
```
c2.\tweak to-right-barline ##t ()
```
