They're completely different methods, though. They're not in a death
struggle :-) They do different things. I wouldn't want to try this
with split:

   "abc   deffff   ghi".squeeze(" f") => "abc def ghi"

squeeze is a better fit, it terms of its stated purpose, than split,
if you want to condense multiple occurrences into one. It's also
faster, in every benchmark I can come up with:

        user     system      total        real
    2.630000   0.010000   2.640000 (  2.665775)
    0.140000   0.000000   0.140000 (  0.136925)

(That's for removing extra " "s from a string of length about 500.)
