f7eaf96eda Fixes bugs. Prepares for conv=sync 
- Splits read fn into conv=sync and standard (consecutive)
  versions.
- Fixes bug in previous read/fill where short reads would copy to wrong
  position in output buffer.
- Fixes bug in unit tests. Empty source would pass (since no bytes
  failed to match).

  Stdout }.
