Explicitly set targetArgument for TermCheck

The `optionsXS` flag defaults to 1 (to enable recursion). What's missing
is the target argument, our sources directory. (It's probably defaulting
to the given value, but we can explicit about this.) We just need to not
override `optionsXS` as we were previously doing with 0 to disable
recursion.
