Re: pandoc adds awkward HTML newlines inside inline verbatim backticks

[John MacFarlane <fiddlosopher-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

I think you'll find this is fixed in recent versions of pandoc. It's always helpful if you say which version you're running when reporting an issue, but I infer it's an older version, because with the current version I get breaks in the right places.  See:

If you don't want to upgrade, there's a simple solution for you:

--wrap=preserve

This will preserve the line breaks in the source markdown instead of automatically rewrapping.

I have teaching materials full of inline verbatim example shell command lines (such as `ls -l /usr/bin`) and I don't want newlines inserted into the middle of those examples, and I don't want them to wrap on output, either.
