t3206-range-diff.sh: cover single-patch case

derrickstolee · gitster · commit cdc067c3197f · 2018-09-12T10:17:42.000-07:00
The commit 40ce416 "format-patch: allow --range-diff to apply to a lone-patch" added the ability to see a range-diff as commentary after the commit message of a single patch series (i.e. [PATCH] instead of [PATCH X/N]). However, this functionality was not covered by a test case. Add a simple test case that checks that a range-diff is written as commentary to the patch.
