There is no need to execute both functions. The underlying
implementation of these functions use `test -e` and `test -f`,
respectively. The former merely checks whether a path exists, whereas
the latter verifies that the path is a file. It follows that when the
path is a file it also has to exist, so using `test -e` (or rather its
wrapper function `test_path_exists`) is redundant.
