It is all in the documentation:
<quote src="-f split">
[...] By default, empty leading fields are preserved, and
empty trailing ones are deleted. (If all fields are empty,
they are considered to be trailing.) [...]
If EXPR is omitted, splits the $_ string. If PATTERN is also
omitted, splits on whitespace (after skipping any leading
whitespace). [...]
As a special case, specifying a PATTERN of space (' ') will
split on white space just as "split" with no arguments does.
[...] "split(/ /)" will give you as many null initial
fields as there are leading spaces. A "split" on "/\s+/" is
like a "split(' ')" except that any leading whitespace produces
a null first field. A "split" with no arguments really does a
"split(' ', $_)" internally. [...]
