Commit b5f5f73 ("[cmdline] Expand settings within each command-line
token individually") introduced a regression into the "isset" command:
it is now possible for command-line arguments to be empty strings, and
so "isset" cannot simply check for a non-empty argument list.
Restore previous behaviour by checking for the presence of any
non-empty arguments, rather than checking for a non-empty argument
list.
