Invalid unitname generated for directories that look like numeric literals about nelua-lang

[stefanos82]

Can you provide a full demo to check it on my side? I have tested the code excerpt you shared and could not reproduce the behavior you shared above.

My bad; I forgot to run the script with 001-example included.

Indeed it would be handy to create something like first-character-breadcrumb appended to script's parent directory; in my case, /home/stefanos/nelua/various/ could become hsnv that could get appended to 001-example.

In other words, it should become hsnv_001_example_f_f(void).

Update as of 16-11-2023: Coincidentally, I have discovered by accident that Crystal language creates a caching directory for improving re-building compilation speeds inside $HOME/.cache/, much like Nelua does, but with the following format: home-stefanos-code-crystal-hello_world.cr/; this is my $HOME/stefanos/code/crystal/ directory with filename hello_world.cr.

This type of format could also be used to avoid the aforementioned buggy behavior while maintaining readability for developers that want to investigate the generate C code and know which file came from where exactly.
