t6032: Add a test checking for excessive output from merge

Previous D/F fixes I submitted (5a2580d and ae74548) had caused merge to
become excessively spammy, which was fixed in 96ecac6 (merge-recursive:
Avoid excessive output for and reprocessing of renames 2010-08-20).  Add a
new test to avoid repeating that mistake with my several upcoming changes.
