But pgpmode=auto is a fine option according to the manpage.


Now, I tried that watchfile trying to understand/fix the warning
reported on https://qa.debian.org/cgi-bin/watch?pkg=inkscape
    Unable to set versionmode=prev for the line without
    opts=pgpmode=prev in debian/watch, skipping:
    https://launchpad.net/inkscape/+download (?:.*/)?inkscape[_\-\.]?(\d\S+)\.(?:tgz|txz|tar\.(?:bz2|gz|z2|xz)).(?:asc|pgp|gpg|sig) previous 
Even if, as you can see in the current watchfile that opts=pgpmode=prev
is set (probably this is some bug, but given it could be my fault I'm
not filing it as so, yet).
