diff.c: omit hidden entries from namelen calculation with --stat

Michael J Gruber · gitster · commit 358e460eebd3 · 2011-05-27T10:44:02.000-07:00
Currently, --stat calculates the longest name from all items but then
drops some (mode changes) from the output later on.

Instead, drop them from the namelen generation and calculation.
