Relevant log output

Start by reproducing the grep comparisons against retroarch.cfg for the AppImage, Flatpak, and Android configurations shown. Establish the intended trailing-slash convention first, since Expected behavior is empty, then trace how these settings are generated. Done means the agreed convention is applied consistently across the listed platforms and verified by rerunning the comparisons.
