[PATCH] Avoid allocating memory to extract basename using svn_relpath_basename

[vijayaguru]

Hi,

  From svn_relpath_basename documentation, if pool is NULL, it simply
returns a pointer to the string without allocating additional memory.
Pass NULL pointer to svn_relpath_basename wherever the returned basename
need not be persistent. It could save few bytes of memory.


[[[
  Log:
  Pass NULL pointer to svn_relpath_basename wherever the returned 
  basename need not be allocated in pool.

        Pass NULL pointer to svn_relpath_basename wherever the returned
        basename need not be persistent.
