Path manipulation functions on Windows

[wanderecon]

Hi Astoff!

Thanks for developing a fantastic package!

I am using lua 5.3.5 (32-bit).

I have installed digestif using luarocks, but have the following error when I try to run digestif in cmd or when it is called in nvim.

I am new to this, so any help would be appreciated!

C:\Program Files (x86)\lua\5.3\bin\lua.exe: ...ram files (x86)\lua\5.3\/share/lua/5.3/digestif\util.lua:322:

This error happens in one of the path manipulation functions. I am not able to test the program on Windows, so I can't fix this. Patches are very welcome, though.

This has been a while ago and the report error location is out of date, so I'll close the issue. Feel free to report similar bugs, if you find any.
