The excluded function uses the static helper excluded_1 to
perform the inner loop over all of the exclude patterns. The
helper just tells us whether the path is included, excluded,
or undecided.
However, it may be useful to know _which_ pattern was
triggered. So let's pass out the entire exclude match, which
contains the status information we were already passing out.
Further patches can make use of this.
