This bug is a bit cumbersome: when we have several windows and do :Explore, the current and the "next" windows display the files in netrw.

This bug appeared on 9.0.1479 if this can help.

Looks like there is a typo in netrws s:NetrwEditBuf() function. This patch fixes it:

diff --git a/runtime/autoload/netrw.vim b/runtime/autoload/netrw.vim

Can confirm, @chrisbra has solved this issue.

Thank you, Christian -- I was attending a wedding without a computer and so couldn't address this.

@cecamp , is it closed because PR created?
I mean I can apply it locally, but I don't want to do it each time after update. :)

Thank you for the fix! :-)
