scripts/get_maintainer.pl: better email routines, use perl not shell where possible
Added format_email and parse_email routines to reduce inline use. Added email_address_inuse to eliminate multiple maintainer entries for the same email address, the first name encountered is used. Used internal perl equivalents of shell cmd use of grep|cut|sort|uniq Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
