It also seems excessive. This is the same thing:

Aside from your regex being longer, I see little to choose between the
two equivalents. One may be slightly faster to execute than the other,
but I wouldn't like to bet on which one, and I hardly see the former as
'excessive'.
On balance I would probably the latter version in my own code, but I
wrote it this way as it was closest to the OP's code of
split /\t\n/;
which was probably incorrect and was confusing people.
