Subject: [PATCH 07/19] perf hists: Return correct number of characters printed in callchain

From: Frederic Weisbecker <fweisbec@...il.com>

Include the omitted number of characters printed for the first entry.

Not that it really matters because nobody seem to care about the number
of printed characters for now. But just in case.
