Bug report

Combination of delimiter=' ' and skipinitialspace=True was considered illegal in #113796, because it is ambiguous in case of empty fields. But there may be a use case for this, when the input is a preformatted table with a series of spaces considered as a delimiter:

apples  red     100
bananas yellow  3

Empty fields are not compatible with such format, so the writer should either quote them, or fail if quoting is not possible.
