I probably do not understand what you two understand, what I don't
understand why should FILE-LIST be appended to empty string, as those
files will not be executed unless they are in path, and unless they
are executables.

! and & should verify if those files are executables -- and if not,
  not execute images and directors -- OR -- maybe developer shall
  decide what is meant with ! or & -- is it maybe meant to execute
  marked files? And if so, then marked files shall be executed in the
  default-directory with prepended ./ and not as general system
  commands searched only in $PATH.
