Running "pacman -Sc" deletes /var/lib/pacman/sync/*.files.sig due to a wrong string length being used when checking filename suffixes in that directory. In turn, these missing signature files cause both the corresponding "*.files" files and their signatures being forcibly re-downloaded again when "pacman -Sy" is executed.
Since official Archlinux repos don't use signed database files yet, this only affects people who use custom repos with signed database files, for which they have set the "SigLevel" directive to "Required" or "DatabaseRequired" in /etc/pacman.conf.
Fixes FS#66472

Awesome! The patch looks great to me.
