What is the path (package.path)?
This feature works with the default value of (package.path).
The gist of this quirk is that both Linux and Windows
ignore superfluous path separators.
For example, the following file
~/My_Lua_Scripts/howling.at.the.lua
is accessible also through another path:
~///My_Lua_Scripts////////howling.at.the.lua
So, the pattern
/usr/local/share/lua/5.3/?/init.lua
after replacing "?" with empty string becomes
/usr/local/share/lua/5.3//init.lua
which is equivalent (from the OS viewpoint) to
/usr/local/share/lua/5.3/init.lua
