Don't turn it into a string here.

fullargs=(grep --color=always -i -- "${grepargs[@]}")
print -rS "$fullargs"
"${fullargs[@]}"

No eval needed, the arguments are now exactly the correct command arguments.

Actually, the

"${stuff[@]}"

is only needed to preserve empty arguments.  It's a good habit to get into,
but you can think about it more simply as just

$stuff

i.e. a set of array elements that turn into a set of command arguments.
