Error when using docker aliases in Windows 10

I'm using Docker on Windows 10. When I try to use aliases like 'ku' I see an error:

bash: cd: too many arguments

If I modify bash_aliases to add quotes around the KOHA_TESTING_DOCKER_HOME variable the commands work:

alias ku='cd "${KOHA_TESTING_DOCKER_HOME}"; \

Is this change something which would be cross-platform acceptable?
