This relies on a patched version of tree to work, unfortunately.
Hopefully upstream will accept our patch.

If `PASSWORD_STORE_DIR:-$HOME/.password-store` is a symlink, Zsh throws:
`_values:compvalues:10: not enough arguments`.

Passing `-L` to find(1) fixes this.

this allows the full entry to be completed with a single tab if there is
only one entry in a folder

e.g., given:

 amazon.com
     user at domain.com
 google.com
     user1
     user2

`pass am<tab>` -> `pass amazon.com/user at domain.com`

while

`pass goo<tab>` -> `pass google.com/`

(previously, the amazon completion would have stopped at amazon.com
despite only a single entry existing)

this allows completing password entries without explicitly typing 'show'
