I tried "all" variations with (?m) (?s) also, and other things. 
Yet it appeared to me so far, that its not the problem with the 
line modes - none of empty matching works with split.

A basic case:
 >>> re.split(r'\b','ab cwoe fds. fi  foiewj')
['ab cwoe fds. fi  foiewj']

He wants at least "something":

 >>> re.split(r'\b.','ab cwoe fds. fi  foiewj')
['', 'b', '', 'woe', '', 'ds', ' ', 'i', ' ', 'oiewj']


While .findXX and .searchXXX are "all-seeing" :

 >>> re.findall(r'\b','ab cwoe fds. fi  foiewj')
['', '', '', '', '', '', '', '', '', '']
