It is, but only after it appeared "naked" in the skeleton.

`skeleton-insert` says:

	str	first time: read a string according to INTERACTOR
		then: insert previously read string once more

which indeed doesn't explicitly tell you tht you're doing something
wrong, but it does imply that `str` doesn't just hold a string, or at
least not initially.

It should work if you can change your skeleton to something like:

    (define-skeleton test-skeleton ""
      (file-relative-name (read-file-name "P: "))
      str
      (shell-quote-argument str))

where that first use of `str` will convert it from something that "read
a string according to INTERACTOR" to the actual string.
