12% of the name/email pairs are messed up. It's not all simple typos.
There is significant mangling of non ASCII charsets by people's tools
in the maintainer's chain of processing. Half of the time I don't
believe what the author is submitting is what is ending up in the log
due to mangling. It's a larger source of noise than typos.

All of these variations on email names are in the log. Humans can
identify these problems, it is much harder for a machine.

For example, where are these backslashes coming from?
Auke-Jan H Kok <auke-jan.h.kok@...el.com>
Auke-Jan H Kok <auke\-jan.h.kok@...el.com>
Auke-Jan H Kok <auke\\-jan.h.kok@...el.com>
Auke-Jan H Kok <auke\\\-jan.h.kok@...el.com>
Auke-Jan H Kok <sofar@...-projects.org>

Are the tools case sensitive or insensitive on email addresses? Some
are are some aren't, so I need these cases...
Al Viro <viro@...iv.linux.org.uk>
Al Viro <viro@...IV.linux.org.uk>
Al Viro <viro@...IV.linux.org.uk>

Another problem is internal machine names...
David S. Miller <davem@...set.davemloft.net>
David S. Miller <davem@...emloft.net>
David S. Miller <davem@...onp11.davemloft.net>
David S. Miller <davem@...ch.davemloft.net>
David S. Miller <davem@...f.davemloft.net>
David S. Miller <davem@...00.davemloft.net>
David S. Miller <davem@...ra5.davemloft.net>
David S. Miller <davem@...a.davemloft.net>

Or varying the email name...
Alexey Starikovskiy <alexey.y.starikovskiy@...el.com>
Alexey Starikovskiy <alexey_y_starikovskiy@...ux.intel.com>
Alexey Starikovskiy <alexey.y.starikovskiy@...ux.intel.com>

Why do these all end in (none)?
Craig Hughes <craig@....rmk.(none)>
Dave Neuer <dneuer@....rmk.(none)>
David Brownell <david-b@....rmk.(none)>
David Woodhouse <dwmw2@....rmk.(none)>
Deepak Saxena <dsaxena@....rmk.(none)>
Enrico Scholz <enrico.scholz@...rmk.(none)>
