[cmdline] Fix multi-layer variable expansion
Expansion of ${${foo}} will currently fail, because the first
opening "${" will be incorrectly matched against the first closing
"}", leading to an attempt to expand the variable "${foo".
Fix by ensuring that the most recent opening "${" is used to match
against the first closing "}".
Total cost: 8 bytes. :)
