The better way (both in zsh and in bash) would be to use an array.

flags=(--untracked --color)
git grep "${flags[@]}" pattern
# git grep $flags pattern   would also work, but just in zsh

Relying on word splitting means that arguments that contain spaces or
other IFS characters are mangled into two or more arguments.
