[PATCH] shell portability: Use sed instead of non-portable variable expansion

Variable expansions like "${foo#bar}" or "${foo%bar}" doesn't work on
shells like FreeBSD sh and they made the test to fail. This patch
replace such variable expansions with sed.

Testing on FreeBSD failed because of this "bash-ism". After applying
this patch, I've verified the test to pass on FreeBSD. (and it worked
well also with GNU sed)
