If you don't want (or with some other example, can't) use the `-a` and `-o`
options of the `test` command, you use the result of chaining commands with
the built-in `and` and `or` by wrapping the entire chain in a `begin; end`
block:
```fish
function xlist
for i in (command ls -1a)
if begin; test $i = "."; or test $i = ".."; end
continue
end
echo $i
end
end
```
