Fix quoting around variables, especially arrays.

Other than pure quoting, this involved:
 - swapping */@ for array access in a few places
 - fiddling with printf in a pipeline
 - replacing `$(echo ${array[@]})` with `${array[*]}`
 - replacing `echo $(...)` with `...`

When searching for these things, I used the command:

    grep -Prn --exclude-dir=.git '(?<!["=]|\[\[ |\[\[ -[zn] )\$(?!{?#|\(|\? )'

and ignored a bunch of false positives.
