bug#72367: srfi-64: nested group not counted as one test

[Tomas Volf]

Hello,

I think I found a bug in (srfi srfi-64) module shipped with GNU Guile.

The specification says the following about the count argument to the test-begin
form:

> The optional count must match the number of test-cases executed by this
> group. (Nested test groups count as a single test case for this count.)

Thus I believe that following should *not* call on-bad-count-function.

    (use-modules (srfi srfi-64))
    (let ((r (test-runner-null)))
      (test-runner-current r)
      (test-runner-on-bad-count! r (λ (runner actual-count expected-count)
                                     (pk (test-runner-group-stack runner))
                                     (pk actual-count expected-count)))
      (test-begin "x" 1)
      (test-begin "y" 3)
      (test-assert #t)
      (test-assert #t)
      (test-assert #t)
      (test-end)
      (test-end))

However as we can see it does:

    ;;; (("x"))

    ;;; (3 1)

Have a nice day
