[pb...@apache.org]

Author: pburba

New Revision: 1480723

URL: http://svn.apache.org/r1480723
Log:
More cleanup to issue #4355 'svn_client_log5 broken with multiple 
revisions which span a rename' fix in r1478220.

Suggested by: cmpilato, julianfoad

* subversion/libsvn_client/log.c

  (svn_client_log5): Fix typo in doc string.  We know what size the output
   array will be, so just initialize it to that size.  Remove an unnecessary
   dereference.

  (convert_opt_rev_array_to_rev_range_array): Replace memcmp comparison of
   two structures with proper member-wise comparison.
