Using a buffer limited to 2048 is unnecessarily limiting. Switch to
using a string buffer to read in stdin for annotation.

As we are reading text, I wonder if it makes more sense to just use
strbuf_getline() that is meant to use the definition of "line" that
honors the platform convention (i.e. on Windows, '\r\n' is taken as
the EOL marker).

Other than that, looking good.

Thanks.
