final manual custo going in the margin

[eroux]

The following example:

\documentclass[12pt, a5paper]{article}
\usepackage{gregoriotex}
\usepackage{fullpage}

\begin{document}

\gresetlastline{justified}
\gabcsnippet{(c4)
Per(h) ip(j)sum,(j) et(j) cum(j) ip(j)so,(j) et(i) in(h) ip(i)so,(i) (;)
est(h) ti(j)bi(j) De(j)o(j) Pa(j)tri(j) om(j)ni(j)pot(j)én(j)ti,(j) (,)
in(j) u(j)ni(j)tá(j)te(j) Spí(j)ri(i)tus(h) Sanc(i)ti,(i) (;)
om(i)nis(i) ho(i)nor(g) et(h) gló(i)ri(h)a(h) (,)
per(g) óm(h)ni(h)a(h) sǽ(i)cu(h)la(h) sæ(g)cu(h)ló(hg)rum.(g) (::)
A(g)men.(gh) (::) (g+)}

\end{document}

gives at the end:

where the custos goes into the margin. This is a problem Solesmes encountered in their latest book (made with Gregorio!)

This may be related to the problem noted in #1273. I have no clue how to fix this.

I think not, I suspect the last double bar gets the wrong type (written by C), but I didn't have time to check...
