including the white space parts in str.split()

[Skaperen]

it is a sequence of characters given in a command argument meant to act similar to the cut command, that parse each line for output. right now a _ is meant to match a run of white space while \_ or in quotes just matches an underscore (in each line of input). i should probably make a version of this that somehow uses regular expressions, though i would have to ask others to test it.
