pacman-db-upgrade: do not mangle file lists
grep'ing out blank lines and sorting output thoroughly breaks any file lists with %BACKUP% entries which must be separated from the file list by a blank line. Adds a custom function to ensure that all paths printed are non-empty and unique. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
