Comments in org babel clojure blocks are not tangled out.

Let us take an example org file with the following contents:-

This org file contains only two source blocks and a total of ten lines.
> #+begin_src clojure :noweb-ref "Define a constant"
>
(def e 2.72)

;;This is a comment on a line of its own
> (def pi 3.14) ;;This is a comment not on a line of its own
> #+end_src

The following block will be tangled
> #+begin_src clojure :noweb yes :tangle ./output.clj
> <<Define a constant>>
> #+end_src


When I tangle the above file, the contents of the output.clj file are:-

> (def e 2.72)


> (def pi 3.14) ;;This is a comment not on a line of its own


*The comment that was on a line of its own is missing from the tangled
output.*

Was able to reproduce on both emacs 29.3.50 and 29.4 on Ubuntu 22.04 LTS
Both were started using *emacs -Q* and then evaluating *(require
'ob-clojure)* as the only line of config.

The contents of the tangled output.clj file were:-

We are missing the comment that was expected in the second line of the
output.
In its place, there is an empty newline.

This seems to be intentional (commit b1f564b4b6):

In ob-clojure.el, we have:

	 ;; Remove comments, they break (let [...] ...) bindings
	 (body (replace-regexp-in-string "^[ 	]*;+.*$" "" body))

It seems that there is some weirdness in Clojure interaction with
comments inside let [...] clauses.

I am not familiar enough with closure to comment on this. Maybe you know
more?

CCing Bastien, the author of the commit.

I guess that we may leave the comments intact if the code block does not
have :var.

I moved the comment stripping code in org-babel-expand-body:clojure to
follow the above idea:-
---
(defun org-babel-expand-body:clojure (body params)
  "Expand BODY according to PARAMS, return the expanded body."
  (let* ((vars (org-babel--get-vars params))
         (backend-override (cdr (assq :backend params)))
         (org-babel-clojure-backend
          (cond
           (backend-override (intern backend-override))
           (org-babel-clojure-backend org-babel-clojure-backend)
           (t (user-error "You need to customize `org-babel-clojure-backend'
or set the `:backend' header argument"))))
         (ns (or (cdr (assq :ns params))
                 (if (eq org-babel-clojure-backend 'cider)
                     (or cider-buffer-ns
                         (let ((repl-buf (cider-current-connection)))
                           (and repl-buf (buffer-local-value
                                          'cider-buffer-ns repl-buf))))
                   org-babel-clojure-default-ns)))
         (result-params (cdr (assq :result-params params)))
         (print-level nil)
         (print-length nil)
         (body (org-trim
                (concat
                 ;; Source block specified namespace :ns.
                 (and (cdr (assq :ns params)) (format "(ns %s)\n" ns))
                 ;; Variables binding.
                 (if (null vars)
                     (org-trim body)
                   (let ((body (replace-regexp-in-string "^[    ]*;+.*$" ""
body)))   ; Remove comments, they break (let [...] ...) bindings
                     (format "(let [%s]\n%s)"
                             (mapconcat
                              (lambda (var)
                                (format "%S '%S" (car var) (cdr var)))
                              vars
                              "\n      ")
                             body)))))))
    (if (or (member "code" result-params)
            (member "pp" result-params))
        (format "(clojure.pprint/pprint (do %s))" body)
      body)))
---

Now, it no longer loses comments on tangling.

The code look reasonable.
Would you be interested to convert it into a patch?
