Problem:
The CST printer emits trailing whitespace after multiline text nodes.
With 1704c604bf and `:cst` corpus tests
this causes trailing spaces to appear on `test --update`.
These spaces cannot be removed afterward, as the test runner
expects an exact character-for-character match for CST tests.
Solution:
Print whitespace only if node is not multiline.

Instead of returning an undocumented boolean flag, use a
core::ops::ControlFlow object. At the expense of being a bit more
verbose, this is a type that should be self-explanatory in the context
of a callback, as an indication of whether to continue processing or
stop.
