No, the code here is fine, and I think chiding people for writing
perfectly find code is counterproductive.  It's not what I'd put in a
general library meant for redistribution, but nobody has any obligation
to write code on any particular form for their own usage.

Besides, `expand-file-name' has annoying corner cases, and Emacs should
really grow a variation that's actually sound and reliable instead of
the current DWIM-ish mess.  For instance, the following loop might
signal an error:

(dolist (file (directory-files "/tmp/"))
  (unless (string-match "^/tmp" (expand-file-name file "/tmp"))
    (error "boom")))

while

(dolist (file (directory-files "/tmp/"))
  (unless (string-match "^/tmp" (format "/tmp/%s" file))
    (error "boom")))

never will.  To see the difference, say

$ touch "/tmp/~$USER"

first.
