I have reworked the patch, please find new version attached. It is 3 
times as smaller than the previous one and now touches pg_rewind's code 
only. Tests are also slightly refactored in order to remove duplicated 
code. Execution of postgres -C is used for restore_command retrieval (if 
-r is passed) as being suggested. Otherwise everything works as before.

Andres, Alvaro does it make sense now?
