At least for this there is an easy solution: Use rehearsal marks
instead of bar numbers. That is, don't write stuff like
```
bla bla | % 1
blubb blubb | % 2
foo bar baz | % 3
urgh | % 4
splish splash | % 5
```
but rather
```
\mark \default % 1
bla bla |
blubb blubb |
foo bar baz |
\mark \default % 2
urgh |
splish splash |
```
If necessary it is straightforward to disable rehearsal marks in the
output after you are done editing.
