Subject: t3509: Add rename + D/F conflict testcase that recursive strategy fails
X-Git-Tag: v1.7.4-rc0~101^2~39^2~1

t3509: Add rename + D/F conflict testcase that recursive strategy fails

When one side of a file rename matches a directory name on the other side,
the recursive merge strategy will fail.  This is true even if the merge is
trivially resolvable.
