I thought it might not work on files contained in subdirectories
but it does. The comma solved the problem with newlines too.

If we leave out the exception checking that's 5 lines of code:

import os, sys, re, fileinput
targetf, original, result = (sys.argv[1]), (sys.argv[2]), (sys.argv[3]) 
for folders, folder, filelist in os.walk(targetf):
    os.chdir(folders)
    for line in fileinput.input(filelist,inplace=1):
        print re.sub(original,result,line),

Compact and elegant !
Tomorrow I'll go about adding the change filename stuff.
