I didn't double check the code that uses the variable, but as long
as the code that uses $reference writs it correctly, e.g.

    git subcmd ${reference:+"$reference"} ...

it should correctly pass what it received in the above assignment
from the user in $1 just fine, even if its value can contain any
arbitrary byte, I would think.
