Steps to reproduce :

```
vim -Nu <(curl https://gist.githubusercontent.com/junegunn6936bf79fedd3a079aeb1dd2f3c81ef5/raw)
:term # Open a new term
:ls
# Shows this :
# 1 a "[No Name]" line 1
# 4 %aR "!/usr/bin/zsh [dougui@oscar: /home/dougui]" line 1
:Buffers
# Shows this :
#> [1] [No Name]
# [4] % !/usr/bin/zsh [+] [RO]
```

As you can see, there is more information in the `:ls`. Principally, there is the running command which can be useful.

I tried to find a useful variable with `getbufvar(bufnr('/usr/bin'), '&')` but I didn't found anything interesting. There is the same problem with `:b `.

Do you have an idea?
