New Revision: 1378193

URL: http://svn.apache.org/viewvc?rev=1378193&view=rev
Log:
* subversion/libsvn_subr/gpg_agent.c
  (receive_from_gpg_agent): Clear the response buffer before attemping
    to read a response from the agent. Prevents this function from
    returning a stale response it obtained during a previous invocation
    in case the gpg agent doesn't respond or sends an empty reponse.
