Percentage width doesn't work with recent texlive

[Philip Taylor]

OK, looking beyond compilation errors (none: the %-sign was clearly not causing a problem), I see :

> Class scrbook Warning: Usage of package `fancyhdr' together with a KOMA-Script class is not recommended. I'd suggest to use package `scrlayer' or `scrlayer-scrpage', because they support KOMA-Script classes. With `fancyhdr' several features of class `scrbook' like options `headsepline', `footsepline' or command `\MakeMarkcase' and the commands `\setkomafont' and `\addtokomafont' for the page style elements need explicite user intervention to work. Nevertheless, using requested package `fancyhdr' on input line 10.

None of those can I help with, I am afraid — they are all LaTeX-specific, about which I know less than nothing.
