In the spirit of making plot and viewmat Just Work TM, would it make sense to
add 'xdg-open' as the initial option in 'dfltpdfreader' and 'dfltimageviewer'?
This mirrors the usage of 'x-www-browser' in 'dfltbrowser'.
For the sake of clarity, 'xdg-open' is a part of the xdg-utils[0] package
typically installed on desktop linux systems. It is a utility designed to open
a given file or URL using the user's preferred application.
Concretely, I am thinking something like this patch relative to 9.1.20:
