Thanks for the suggestion, but adding \] does not really fix the problem, it
just masks it in many cases (better than nothing).
The \[ \] wrappings are required. They're not "masking" the problem.
Your prompt is literally set incorrectly without them.
Agreed that \] is required. With "masking" I mean that the use of \]
prevents the problem I'm referring to from showing up easily. But the
problem is still there even when \] is used.
The following snippet shows that, even with the final \], Bash produces
the same erroneous output and miscalculates the cursor position (it just
needs a longer prompt):
$ long_name="$(printf 'abcdef0123456789/%.0s' {0..20})"
$ mkdir -p /tmp/$long_name
$ cd /tmp/$long_name
$ PS1=$'\n\[\e[1m\]\w\[\e[m\] \$ '
Now press the up arrow, then the down arrow)
