Issue Description:
When you type:
$ xcrun swift-demangle
< input1
< input2
< Ctrl+D
> output1
> output2
You don’t get any output until you Ctrl+D to close the stream. Could we make swift-demangle incremental line by line (or \0 by \0 if needed)? I.e.:
$ xcrun swift-demangle
< input1
> output1
< input2
> output2
< Ctrl+D
This would have general memory usage and performance goodness for piped code.
