t3200: prepare for main being shorter than master

dscho · gitster · commit 56300ff356bf · 2020-10-23T08:57:41.000-07:00
In the test case adjusted by this patch, we want to cut just after the
longest shown ref name. Since `main` is shorter than `master`, we need
to decrease the number of characters. Since `topic` is shown, too, and
since that is only one character shorter than `master`, we decrement the
length by one instead of two.
