Just put everything in a shell script. (That way you can test it directly
without systemd, too.)

With bash, you can use inline comments in arrays:

#!/usr/bin/env bash
args=(
    -X POST                     # foo
    -d "fizz=systemd"           # some docs
    -d "some=else"              # more docs
    https://requestb.in/foo
)

exec curl "${args[@]}"
