Subject: [PATCH] MAINTAINERS: merge P and M fields to ease copy'n'paste

This was suggested by Sam Ravnborg and done using the following
Python script:

	#! /usr/bin/env python

	import locale
	import re
	import sys
	import tempfile

	locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

	re_person = re.compile(r'P:(\s*)(.*)')
	re_mail = re.compile(r'M:\s*(.*)')

	fixed_maintainers = tempfile.TemporaryFile()

	current_persons = None
	current_persons_used = False

	for lineno, line in enumerate(open('MAINTAINERS')):
	    mo = re_person.match(line)
	    if mo:
	        if current_persons and not current_persons_used:
	            print >> fixed_maintainers, 'P:%s%s' % (current_persons_intend, ', '.join(current_persons))

	        current_persons = re.split(r',\s*', mo.group(2))
	        current_persons_intend = mo.group(1)
	        current_persons_used = False
	        continue

	    mo = re_mail.match(line)
	    if mo:
	        if current_persons is None:
	            print 'mail without person at line %d' % (lineno + 1)
	            sys.exit(1)

	        mail = re.split(r',\s*', mo.group(1))

	        if mail == ['Mail patches to']:
	            mail = ['p.e@...on']

	        if len(mail) != len(current_persons):
	            if len(mail) == 1:
	                current_persons = ['%s' % ', '.join(current_persons)]
	            elif len(current_persons) == 1:
	                current_persons = len(mail) * current_persons
	            else:
	                print 'number of persons doesn\'t match number of mail addresses at line %d' % (lineno + 1)
	                sys.exit(1)

	        print >> fixed_maintainers, 'P:%s' % current_persons_intend + ', '.join('%s <%s>' % pm for pm in zip(current_persons, mail))
	        current_persons_used = True

	    else:
	        if current_persons and not current_persons_used:
	            # either there is no mail address or the entry is already correct
	            print >> fixed_maintainers, 'P:%s%s' % (current_persons_intend, ', '.join(current_persons))

	        current_persons = None
	        print >> fixed_maintainers, line,

	fixed_maintainers.seek(0)

	maintainers = open('MAINTAINERS', 'w')
	for line in fixed_maintainers:
	    print >> maintainers, line,

I deleted the actual patch to save some bytes.  To get the real patch
you have several possibilities:

 a) look at http://modarm9.com/git/people/ukleinek/linux-2.6.git?a=commit;h=33c64dab660857949c9a78f2a8edca14d30455c5;
 b) fetch/pull from the maintainers branch at

 	 git://www.modarm9.com/gitsrc/pub/people/ukleinek/linux-2.6.git maintainers

    ; or
 c) extract the script above and apply it

Note that a) and b) probably stop working in the future.

Best regards
Uwe
