So put the internal \" where you want it, instead of at the end. :-)
transport_filter = "\"arg0...\" arg1 arg2"
or whatever.
Alternatively, you can use single quotes if you don't need any escaping
within the string. (See documentation for the "command" option of the
pipe transport (29.2) - the documentation for "transport_filter" points
out that it is handled in the same way.) In other words, it's all in TFM
if you know where to look...

No. The split happens first so that the result of an expansion cannot
affect the number of arguments. Each argument is separately expanded.
