Re: easier construction of arrays

[Dan Douglas]

I don't believe any shell can currently read nul-delimited input into
an array without looping. It's been suggested to add a delimiter to
mapfile. It looks like mapfile uses zgetline() to wrap around calls to
zread() and doesn't support any delimiter. read(1) on the other hand
uses one of the zread functions directly depending upon what it's
trying to do. I would guess there are some performance differences.
