Public bug reported:
The program stops with an error
[1] 673467 segmentation fault (core dumped) tree . 2
If the second argument does not exist. The program behaves correctly if
it's the first argument that does not exist instead (e.g. `tree 2 .`).
I ran into this by confusing -L 2 for -d 2 and typed `tree . -d 2` which
produces the segmentation fault instead of showing an error as "2" isn't
a valid directory.
