TIL: `a=(m e o w); echo ${a[@]/ /}` results in spaces still being there, because the replace is being run per element, not per output string

this also means that for `a=(m m m m); b=mmmm`, running `${a[@]/m/}` is different than `${b/m/}`

(first one results in an empty string, second one is just `mmm`)
