I don't see the point of removing the quotes.

If the name and email address don't exactly match,
why shouldn't it be reported?

Perhaps better to show the From: line author

"Missing 'Signed-off-by:' from nomimal patch author '$author'\n");

Another somewhat frequent Signed-off-by: defect pattern
is to have a lower-case name or no name at all used.

Perhaps it'd be useful to add some checks like
a single word for a name and all lower-case names:

e.g.:
Signed-off-by: joe perches <joe@perches.com>

emits

Unusual lower case name: 'joe perches <joe@perches.com>'

and
Signed-off-by: root <root@mydomain.net>
and
Signed-off-by: Root <root@mydomain.net>
and
Signed-off-by: root@mydomain.net

all emit that a single or missing name is unusual.
