This doesn't seems fixed in 2.17.10

I now get:

Use of uninitialized value $lastversion in concatenation (.) or string 
at /usr/bin/uscan line 2738, <WATCH> line 7.
uscan warn: Unable to set versionmode=prev for the line without 
opts=pgpmode=prev
   in debian/watch, skipping:
   https://red.libssh.org/projects/libssh/files 
/attachments/download/(?:\d+)/libssh-[-_]?(\d[\-+\.:\~\da-zA-Z]*).tar.asc 
previous

There is an extra perl error here

(and the missmatch between pgpmode=prev and pgpmode=previous is still here)
