comment inconsistent: fs/parent returns file no matter if it exist or not

[jeroenvandijk]

(Tested with babashka/fs {:mvn/version "0.4.19"})

Comment says: Returns parent of f, is it exists. Akin to dirname in bash. (source)

Except for the typo, "if it exists" is not correct:

E.g.

(def f (fs/file "a/b/c"))
(fs/exists? f) ;=> false
(fs/parent (fs/file f)) ;=> (fs/file "a/b")
(fs/exists? (fs/parent (fs/file f))) ;=> false

This is consistent with java.io.file behaviour though:

(.getParentFile (java.io.File. "non-existent/dir/foo")) ;=> (java.io.File. "non-existent/dir")
