one additional observation which, as brent butt of "corner gas" would
say, "oh ... well, that in no way explains it."

$ dos2unix a/b/c/d/e/file.c
  (success)

$ cd a
$ dos2unix b/c/d/e/file.c
  (success)

$ cd b
$ dos2unix c/d/e/file.c
  ... above error ... ???

$ cd c
$ dos2unix d/e/file.c
  (success)


duh?
