On the other hand, often you *don't* want the eval, because then
something like
repeat 5 make CFLAGS="-g -O"
or
file="name has spaces.txt"
repeat 5 scp "$file" "$host:$dir/"
fails. That's why my second offered replacement function uses "$@"
by default but has a -e option to do an eval. I think that's the best
way to go, personally.
