issue with building a command-line and prevent globbing by quoting parameter expansion, solution: use array.

```
#!/usr/bin/env bash
function test() {
  echo "${@}"
}
function blaat() {
  local flags
  test hello "${flags[@]}"
}
function blaat1() {
  local flags
  flags=(a b c)
  test hello "${flags[@]}"
}
blaat
blaat1
```

```
❯ bash /tmp/tmp.qI8lPlBQUe
hello
hello a b c
```
