Hi, I hope this org file is descriptive enough along with the subject.

I'm using org 9.5.2.

I believe it might be a bug since the results of calling =all-tangled-filepaths= only has 4 results, so the =org-babel-expand-src-block= function might have a bug.

* Show files I tangle and could delete from git
** currently not working and outputting weird stuff
*** The expansion seems to include an empty result for some reason

#+begin_src emacs-lisp :results verbatim
  (save-excursion
    (progn
      (goto-char
       (org-babel-find-named-block "files-to-remove-from-git"))
      (org-babel-expand-src-block)
      ))
#+end_src

#+RESULTS:
#+begin_example
"git ls-files ~/system/users/profiles/emacs/default.nix
git ls-files ~/system/users/profiles/emacs/emacs-packages.nix
git ls-files ~/system/users/profiles/chat/default.nix
git ls-files ~/system/profiles/misc/default.nix
git ls-files "
#+end_example
*** here's what hapepns if we just run =all-tangled-filepaths=

#+call: all-tangled-filepaths()

#+RESULTS:
: ~/system/users/profiles/emacs/default.nix
: ~/system/users/profiles/emacs/emacs-packages.nix
: ~/system/users/profiles/chat/default.nix
: ~/system/profiles/misc/default.nix

** get tangled blocks

#+name: all-tangled-filepaths
#+begin_src sh :results output
rg -N -o  ' :tangle ([^yesno][^ ]+)' -r '$1' ~/.emacs.d/system.org  | rg '/system/'
#+end_src

** pass those to git-ls-files

#+name: files-to-remove-from-git
#+begin_src sh :noweb yes :dir ~/system
git ls-files <<all-tangled-filepaths()>>
#+end_src

  This is because noweb automatically appends text before <<...>> to each
  line of multi-line noweb expansions.
  See https://orgmode.org/manual/Noweb-Reference-Syntax.html
  
  On the latest Org, this behaviour can be disabled using :noweb-prefix no
  header argument.
