Upstream declined re-adding the format lenght parameter, but it's rather for
design reasons:

-->
I don't remember any specific reasons about this one, just that we removed a
whole bunch of magic string mangling; we did not want udev provide shell-like
features. People asked for more
of them, and we thought they should use a shell, if they need to do more
complicated things.
[...]
I think we should have less string mangling support in udev rules, not more.
hence, let's not add this, I see little point in restoring something that was
removed 8 years ago and nobody
noticed or missed so far.

Closing. I hope this makes sense.

Question is where we go from here. Should we add a suse-only patch or move the
funbctionality to an external script/binary?
Franck, any thoughts?
