^^
I believe if Title were added there'd be an extra line once the
following dashes are printed (end w/ \n, start with \n)

It does seem in the expected virshtest.c output we're still off by 1.
That is there is 1 more "-" than extra space after the State column.
[1]
Instead of counting dashes...
dashcount = 45; /* Or some value - whatever it is */
...
if (optTitle) {
...
dashcount += 20;
}
,,,
for (i = 0; i < dashcount; i++)
buf[i] = '-';
vshPrintExtra(ctl, "%s\n", buf);
...
where of course buf is appropriately defined ;-) A nit would be that
the old output was 3 dashes longer.
ACK with at least the fixup as a result of having Title on the line (and
it would be nice to add a test for it too)!
Whether you implement the '-' hack is up to you, but it may make future
adjustments more simple...
