fix: pipestatus quoting on Zsh/Bash (#3088)

Browse Source 
Changes the parsing for pipestatus to allow for multiple arguments, a
single argument of space-separated values, or any mix of the two. All
inputs are flattened into a single array where no elements have spaces
in them.

Changes the initscripts to no longer fail when an empty pipestatus
is passed as an argument by quoting and changing expansions.
