Bug 17913: Run perltidy on the inner foreach loop

Kept the same number of lines.
You could verify with diff -w.

Test plan:
[1] Run t/db_dependent/Authorities/Merge.t
[2] As the last patch in this series, also test the interface:
    Set AuthorityMergeMode to loose. Set dontmerge to Do.
    Modify an authority record attached to multiple biblios.
    Edit a subfield, clear a subfield and add a subfield.
    Save. Wait a bit for the merge and Zebra update.
    Verify that the changes are merged properly into biblio records.
[3] Repeat step 2 with AuthorityMergeMode to strict.
    Remember that this affects the extra subfields in biblio records.
