While this is true, it probably covers the major OS-es there. If you are 
on more obscure OS, you would be already more aware.

For sure LuaFileSystem does not cover how to handle windows filename 
with space at the end :)

Even using Windows functions (GetFullPathName) would fail you in this 
very rare case.

(For example if you want to delete such Windows file with spaces to the 
end, then you have to turn all / to \, remove duplicate ones, and 
prepend \\?\ to the name -e .g. "\\?\C:\somefile.txt " - without the 
quotes).

Hardly anyone could handle this special case, on the most desktop 
popular system.

And please let's not go the Common Lisp way, supporting even versioning 
(not that Windows does not have it - through streams, and I use it 
actively, but still).
