"Format" should refer to syntax *and* semantic. So if we do an
incompatible change in how things are interpreted, we should give a new
version number. 

And the old format allowed (at least factically) also to end lines with
a backslash, while the new format is in contrast strict Deb822.

You may now upgrade Debian Med tasks as well with the "-U" flag.

The check for availability happens later (in the "fix_dependencies()" method).

I do the development in my personal salsa project:


You can take out "blends.py" there and use it as blend-gen-tasks. Take
care since some flags are changed, and the tool directly writes the
files instead of dumping to stdout.
