Subject: [PATCH v2 1/6] t4200: give us a clean slate after "rerere gc" tests

From: Junio C Hamano <[email-masked]>
Date: Tue, 22 Aug 2017 14:46:47 -0700

The "multiple identical conflicts" test counts the number of entries
in the rerere database after trying a handful of mergy operations
and recording their resolutions, but without initializing the rerere
database to a known state, allowing the state left by previous tests
to trigger a false failure.  Make it robust by cleaning the database
before it starts.
