[PATCH 2/4] base-files/functions.sh: do not iterate over ls

[Rosen Penev]

>From https://github.com/koalaman/shellcheck/wiki/SC2045 :

When looping over a set of files, it's always better to use globs when
possible. Using command expansion causes word splitting and glob
expansion, which will cause problems for certain filenames (typically
first seen when trying to process a file with spaces in the name).
