sub() got an unexpected keyword argument 'flags'

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run in python2.6
2. There are four lines of code that look like this:
color += re.sub('(.).',lambda m: m.group(1),line, flags=re.DOTALL)
3. Observe a crash, as the flags parameter was introduced in the sub() method 
in Python 2.7

What version of the product are you using? On what operating system?
1.7 on Linux

Please provide any additional information below.

I think this can be fixed like this:

foo = re.compile('(.{3}).',  flags=re.DOTALL)
color += foo.sub(lambda m: m.group(1),line)

Confirmed, changing the re code like this, fixes it for 2.6.

Outside the for loop:
re1 = re.compile('(.).', flags=re.DOTALL)
re2 = re.compile('.(.)', flags=re.DOTALL)

Inside the for loop:
color += re1.sub(lambda m: m.group(1),line)
alpha += re2.sub(lambda m: m.group(1),line)

Same deal on the next set:

re1 = re.compile('(.{3}).', flags=re.DOTALL)
re2 = re.compile('.{3}(.)', flags=re.DOTALL)

color += re1.sub(lambda m: m.group(1),line)
alpha += re2.sub(lambda m: m.group(1),line)
