Insert brackets, lines and arrows between chord names

[Javi]

Hi, I'm trying to make a harmony analysis of some jazz standards with 
lilypond.


I have a jazz lead sheet with Chord Names and some numeral Romans under 
the staff based on the lilypond-roman-numeral-tool. 
https://github.com/davidnalesnik/lilypond-roman-numeral-tool


Now I need a way to insert brackets, arrows or lines between chords 
names in order to express the direction and function of every chord as 
it is usually done in jazz harmony.


Is there any way of doing this?

Why slurs and not ties?

Indeed, this looks like a bug.  However, a simple solution is to do
the following – but I guess you know this already :-)

```
\version "2.25.0"

\relative c'' {
  b4 b b
  4 ~ 
  2. ~ 2
}
```
