Daniel Rainer 414dba994f io: accept intoCharIter in more functions ...

This makes them more general than the previous versions which expected
`&wstr`. It comes at the cost of additional eager calls to `chars()`.

To implement `appendln` without having to call `append` twice, implement
`IntoCharIter` for chained iterators whose elements are both the kind of
iterator specified by `IntoCharIter`.

Because `IntoCharIter` is not implemented for owned types to avoid
allocations, some call sites which used to pass `WString` need to be
updated to pass references instead, which constitutes the bulk of the
changes in this commit.
