From the top of my local repo, I performed the following:

grep -rn "\\\n\\\r" . | grep printf | grep -v sprintf

The results are limited to a handful of modules:

applications/gtk3-tqt-engine
applications/kcmldap
applications/kcmldapcontroller
applications/kcmldapmanager
applications/kgtk-qt3
applications/knetworkmanager8
applications/knetworkmanager9
applications/koffice
applications/qt4-tqt-theme-engine
applications/smartcardauth
libraries/libtdeldap
tdelibs/tderandr
tdenetwork/wifi/kcmwifi
tdepim/tderesources/caldav
tdepim/tderesources/carddav

I did not want to interfere with any additional work you were 
doing, which is why I asked rather than start patching. :-)
