Arrow direction in pretty-printed stacks

Related Problem

I looked through issues in case there was already a discussion about it, but didn't manage to find anything - please point me to it if there was one.

Currently, the printed report looks something like this

external error
├╴at src/main.rs:29:20
│
├─▶ intermediate error
│   ╰╴at src/main.rs:21:21
│
╰─▶ internal error
    ╰╴at src/main.rs:13:23

This seems a bit confusing from the design perspective - it implies that there is some data flow going on from the external error to internal ones.

Proposed Solution

I wonder, wouldn't it be more intuitive if it looked something like this:

external error
╰╴at src/main.rs:29:20
▲
└── intermediate error
┌─▶ ╰╴at src/main.rs:21:21
│
╰── internal error
    ╰╴at src/main.rs:13:23

or this:

external error
╰╴at src/main.rs:29:20
▲
└── intermediate error
▲   ╰╴at src/main.rs:21:21
│
╰── internal error
    ╰╴at src/main.rs:13:23
