Subject: bug#62543: [PATCH] bs support for project.el

From: Philip Kaludercic <[email-masked]>
Date: Thu, 30 Mar 2023 12:27:33 +0000

This is a quick attempt at adding support for project.el to bs.el.  It
works well when bs-show is invoked in a project directory, but if you
open it outside of a project all you get is the current
file/directory -- this doesn't make that much sense to me, but I don't
know what would be better?
