The expectation is from the man page "...Consecutive spaces and tabs count as
one single field separator" so ther should be no change of the type of white
space. If the first of the series of white space is a tab, regardless the other
whitespaces should be deleted. The same if the first is a white space is a
space. This would also be logical: reduce a series of whitespaces regardless
what type to a single one.

As there is a different behaviour also in the usage with the field numbers, I
am pretty sure that it is a bug. The bug has two sub-bugs: I would not expect
the change of the leading white space type ( but that could be a feature that
could be described in man) and the second , that it has diffrent behaviour when
the number of fields is not given.

At least a useful workaround could be to update man: "-w Use whitespace (spaces
and tabs) as the delimiter.  Consecutive spaces and tabs count as one single
field separator. All consecutive field separator will be replaced with a single
tab when used with a known range of fields"
