The following patch adds a short description of the os.sleep() function which is undocumented to the manual. The C source code of the os.sleep() function can be found here: https://gitlab.lisn.upsaclay.fr/texlive/luatex/-/blob/master/source/texk/web... In addition, the patch documents the optional argument template of the os.tmpdir([template]) function: https://gitlab.lisn.upsaclay.fr/texlive/luatex/-/blob/master/source/texk/web... The patch also fixes a few whitespace issues.
