Subject: [PATCH v3 10/12] git-gui: allow specifying path '.' to the browser

From: Mark Levedahl <[email-masked]>
Date: Sun, 31 May 2026 19:02:23 -0400

Invoking "git-gui browser rev ." should show the file browser for the
commitish rev, starting at the current directory. When the current
directory is the working tree root, this errors out in normalize_relpath
because the '.' is removed, yielding an empty list as argument to [file
join ...]. git ls-tree (underlying the browser) accepts '.', so use that
as the value when in the root.
