Fix '=' alignment and replace tabs in *.conf (whitespace only change)

Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.

The work was mostly done using the following python script (might
come in handy again...):

import sys, re
indent_eq = 25 + 0*4 # 25 characters was the most widely used indentation for the '=' character
p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')

for fn in sys.argv[1:]:
    with open(fn, 'r+') as f:
        lines = []
        nl_count = 0
        continuity_indent = None
        for l in f:
            m = p.match(l)
            nl = l
            if m:
                n_spaces = max(m.start(3), indent_eq - 1) - len(m.group(2)) - len(m.group(1))
                if m.group(2) and m.start(2) >= indent_eq-1 and m.start(2) % 4 == 0:
                    n_spaces -= 1 # left-shift '+=' by one if the '+' is aligned to a multiple of 4
                n_spaces = max(1, n_spaces) # we want at least one space before '='/'+='
                nl = m.group(1) + ' '*n_spaces + ''.join(m.group(2,3,4)) + '\n'
                continuity_indent = nl.find('= ') + 2 if l[-2] == '\\' else None # remember indent on '\\$'
            elif continuity_indent:
                nl = ' '*continuity_indent + l.lstrip()
                if l[-2] != '\\': # check when to stop the continuation
                    continuity_indent = None
            elif l.startswith('#'):
                nl = l.expandtabs(2)
            if l != nl:
                nl_count += 1
            lines.append(nl)
        if nl_count > 0:
            print fn, nl_count, len(lines)
            f.seek(0)
            f.writelines(lines)
            f.truncate()
