Ah, there is a bug indeed! If there are three arguments to
`\fill-line`, and the first argument collides with the third argument,
the latter gets moved into the right margin, which is inconsistent
behaviour in comparison to the two-argument case.
```
\version "2.25.25"
\markup \fill-line {
"Leeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeft"
""
"Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiight" }
{ a' }
\markup \fill-line {
"Leeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeft"
"Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiight" }
{ b' }
\paper {
line-width = 100\mm
ragged-right = ##f
indent = 0
}
```
