This mimics the same behaviour as "ls ~" in the shell, which expands the alias
as a directory, and not as a filename. For the specific edge-case where a
filename called "~" must have a path constructed to it (e.g. "./~" or "~/~").

If a resource path is already set in the image, don't change it. Should make #364 work a bit more as expected, and let us set the resource path for deployed Mac OS X bundles.
* Change the interface of read-into to return a slice and an eof boolean separately so the compiler can optimize the slice.
* Add an each-stream-block-slice combinator that behaves like each-block but reuses a preallocated buffer for every iteration.
* Pull some strings in the stream-read-into implementation to further improve type propagation and bounds check elimination.
We also need to save C ABI volatile registers before calling the signal handler in order to be able to reliably resume. Add signal-handler and leaf-signal-handler subprimitives to preserve volatile registers before invoking the signal handler C function.
* with-error-stream(*)
* with-output+error-stream(*) -- sets output and error stream to same stream
* with-output>error -- sets output stream to error stream for scope
* with-input-output+error-streams(*) -- like with-streams, but sets output and error to same stream
Implement M: utf16[bl]e encode-string to use a fast implementation if a string is ASCII only, and do some inlining so the slow path optimizes a bit better.
stream-contents is extremely slow on decoder streams when implemented with each-block, and it can be implemented very quickly for streams of known length using stream-read-unsafe. Make it generic and provide some off-the-shelf implementations using each-block, a read1 loop, or length + read-unsafe. Provide new stream-seekable? and stream-length generics that can be implemented by stream implementations that know their size.
Now that "io" provides a method on object for stream-read-partial-unsafe that forwards to stream-read-unsafe, individual stream class that don't implement partial reads don't need to provide such a method themselves.
Provide default implementations of all the input-stream methods in terms of stream-read1 and of all the output-stream methods in terms of stream-write1.
Now that all streams have been updated to implement the stream-read-unsafe protocol, take out the noncopying-reader shim. Turn stream-read and stream-read-partial into plain functions over the -unsafe generics.
