Add backslash to list of 'crud' characters in real name

Add backslash to list of 'crud' characters in real name

[Linus Torvalds]

We remove crud characters at the beginning and end of real-names so that 
when we see email addresses like

	From: "David S. Miller" <davem@davemloft.net>

we drop the quotes around the name when we parse that and split it up into 
name and email.

However, the list of crud characters was basically just a random list of 
common things that are found around names, and it didn't contain the 
backslash character that some insane scripts seem to use when quoting 
things. So now the kernel has a number of authors listed like

	Author: \"Rafael J. Wysocki\ <rjw@sisk.pl>

because the author name had started out as

	From: \"Rafael J. Wysocki\" <rjw@sisk.pl>

and the only "crud" character we noticed and removed was the final 
double-quote at the end.

We should probably do better quote removal from names anyway, but this is 
the minimal obvious patch.
