RFC: make MAINTAINERS email addresses easier to copy/paste

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

I like to use display names for email addresses, e.g.,
"Bjorn Helgaas <bjorn.helgaas@hp.com>" instead of just
"bjorn.helgaas@hp.com".

The current MAINTAINERS file format makes it a nuisance to
copy both the display name and the actual address.  So
I propose that we fold together the current "P:" and "M:"
lines using something similar to the filter below.

If we do this, we should fix a few inconsistencies in the
current file first so the script will work better.  I'll post
a patch to do that as a response to this message.

# Combine name and email address for easier copy and paste.
# For example, this:
#
#	P:	Bjorn Helgaas
#	M:	bjorn.helgaas@hp.com
#
# becomes this:
#
#	P:	Bjorn Helgaas <bjorn.helgaas@hp.com>

    if (/^P:(\t|\s{2,})(\S.+)/) {
	if (defined($line)) {
	    print $line;
	    undef $line;
	}
	$name = $2;
	$line = $_;
    } elsif (/^M:(\t|\s{2,}).*?(\S+@\S+)/) {
	if (defined($line)) {
	    $mail = $2;
	    $mail =~ s/^<//;
	    $mail =~ s/>$//;
	    print "P:\t$name <$mail>\n";
	    undef $line;
