[ELPA Syncer]

branch: externals/org
commit 1ad16ffb95ee1434ccc49ac553b895b37471f3cb
Author: Jeremie Juste <djj@debian-BULLSEYE-live-builder-AMD64>
Commit: Jeremie Juste <djj@debian-BULLSEYE-live-builder-AMD64>

    ob-R.el: Restore the handling of org-list in as var
    
    * ob-R.el (org-babel-R-assign-elisp): Use the patch from
    ccberry@health.ucsd.edu, to print org-list as a one column table as it
    was the case in release_9.5. The break in R is due commit b4e437f96 *
    ob-core: Resolve named list references to simple lists.
    
    * test-ob-R.el (ob-R-nested-list): New function to test that org list
    with multiple level are handled as expected in R.
    
    see https://list.orgmode.org/87bkofh0ir.fsf@localhost/ for context.
