[dvipdfmx] Fw: Re: [tex-k] dvipdfmx: Apparent bug

[Laurence Finston]

This is the version I'm using:

dvipdfmx --version
This is dvipdfmx Version 20190824 by the DVIPDFMx project team,
modified for TeX Live,
an extended version of dvipdfm-0.13.2c developed by Mark A. Wicks.

Copyright (C) 2002-2019 the DVIPDFMx project team

I tried to see what the current version was but it wasn't as straightforward as I thought it would be, i.e.,
I couldn't just browse a repository or download a tarball with the sources for TeXLive that wasn't huge.
Maybe I'm missing something, though.
