Title: Avoid bash's variable unbound error

When I use bash's option nounset (It can be enable by "set -o nounset"),
running commands of scm_breeze get errors like below.
"-bash: e4: unbound variable"
"-bash: scmbDebug: unbound variable"

I just avoid from error situation by make variable empty if specific variable unset.

If you think proper solution for this error situation. please notice me.
thank you.
