`breakbefore` and `breakafter` not work for excessive sequence of same characters

[muzimuzhi]

\documentclass{article}
\usepackage{fvextra}

\begin{document}

\begin{Verbatim}[breaklines,breakafter=-]
-------------------------------------------------------------------------------
\end{Verbatim}

\begin{Verbatim}[breaklines,breakafter=-,breakbefore=-]
-------------------------------------------------------------------------------
\end{Verbatim}

% only `breakanywhere` succeeds
\begin{Verbatim}[breaklines,breakanywhere]
-------------------------------------------------------------------------------
\end{Verbatim}

\end{document}

For cases like this, you need breakbeforeinrun and breakafterinrun to allow breaks within runs of identical characters.

It looks like some unnecessary breaks are inserted...it might be possible to improve things so that those are prevented.

Thanks! breakafter=-,breakafterinrun works like a charm.

I also noticed that the docs of breakbeforeinrun and breakafterinrun in minted is misleading and different from those in fvextra. I've opened gpoore/minted#408 to fix it.
