The Edebug spec for seq-let is incorrect, causing code that uses it to
not work correctly while instrumented for debugging.
To reproduce:
1. emacs -Q
2. enter the following code into *scratch*:
(defun seq-let-bug ()
(let ((nums [1 2 3 4 5]))
(seq-let (a b c) nums
(message "a=%s b=%s c=%s" a b c))))
3. C-u C-M-x
4. M-: (seq-let-bug) RET
Result: a=nil b=nil c=nil
Expected result: a=1 b=2 c=3
Changing seq-let's edebug spec to (debug (sexp form body))
fixes this for me.

I left out a couple of steps, so please use this sequence to reproduce
the bug:
1. emacs -Q
2. M-: (require 'seq) RET
3. enter the following code into *scratch*:
(defun seq-let-bug ()
(let ((nums [1 2 3 4 5]))
(seq-let (a b c) nums
(message "a=%s b=%s c=%s" a b c))))
4. C-u C-M-x
5. M-: (seq-let-bug) RET
6. G
After step 5 the debugger prompt will appear, so the G is to make it
continue execution without stopping.

Indeed, thanks for reporting!

Why sexp instead of form for the first argument?
Cheers,
