Meanwhile, I was experimenting with the following Lua script to be run with texlua:
This prints nil as you reported. On the other hand, if the script is changed into
I get (Mac OS X, TeX Live 2017, kpathsea version 6.2.3)
lstat(./kpsewhich --format=lua) failed ...
./kpsewhich --format=lua: No such file or directory
Assertion failed: (ret), function remove_dots, file ../../../texk/kpathsea/progname.c, line 316.
