Your latest suggestion is probably easier, so we could take it for
LaTeX-mode.  I didn't have the time to check my proposal in docTeX-mode,
so I applied your patch and did it now with this test file:

--8<---------------cut here---------------start------------->8---
% \iffalse
%<*driver>
\documentclass{ltxdoc}
\usepackage[T1]{fontenc}
\usepackage{etoolbox}
\usepackage{iftex}
\begin{document}
\DocInput{minimal-dtx.dtx}
\end{document}
%</driver>
% \fi
%
% Here is some text with \verb|longer inline verbatim input in one line|
% and now the same thing with
%
% Here is some text with |longer inline verbatim which does break over
% a line|
%
% \endinput
% Local Variables:
% mode: doctex
% TeX-master: t
% End:
--8<---------------cut here---------------end--------------->8---

ltxdoc.el adds '|' to `LaTeX-shortvrb-chars' but fontification of \verb
macro and verbatim-environment doesn't work with docTeX.  I think your
proposal doesn't work there for the same reason.  Maybe we can try to
address this issue as well.

And while we're at it, I think there is also a bug in docTeX-mode which
indents verbatim environments like this:

% \begin{verbatim}
% foobar
% \end{verbatim}

Note the spaces inserted, most notably before the content which means
that it will be inserted in the final product.  I will see if adding it
to `docTeX-indent-inner-fixed' fixes the issue.

Yes, we can ;-)

Best, Arash
