Before seeing your email, I noticed palapeli was 136MB and tried to shrink 
the files. I tried both recompressing the gzipped .puzzle files with
advdef -z4, and *de*compressing them to let git do compression/delta as we 
plan to do for SVGs, but nothing helped, at least not enough.

I can also reproduce these results: removing the .pala and .puzzle files 
makes the repository a mere 3.6MB.

So I agree with removing them. But I'm not sure if we should have a 
palapeli-history repo; maybe we should simply tell people to grab the old 
files from SVN history if they want them. As far as I know, SVN isn't going 
away anytime soon.

There is also precedent for this: look at kdeedu/kstars-filter and 
bin/deleter-fb in the kde-ruleset repository.
