[QE-developers] proper directory delimiters under windows

Hello
did you ever try to use WSL in windows ? Running qe in the WSL is
usually much less complicated than running the windows executables.
It seems also that this is the way microsoft wants to use more and
more for supporting programs like qe in Windows. There are also
programs (e.g. IDEs like pycharm and vscode) whose interface runs on
windows while they execute code inside the WSL, the GUIs might do
something like that in the future versions.
So I am not sure how worth it is to invest time in trying to add a path
management of our own in the code ( currently it is done by the compiler
), and it seems, to me, also not that easy to do.
regards
Pietro
