Revision 1905760

On the 'pristines-on-demand-on-mwf' branch: In svn_wc_crawl_revisions5(),
do not return SVN_ERR_WC_DEPRECATED_API_STORE_PRISTINE unless this
deprecated function is called with restore_files set to true.

Other usages of this function, except when restoring files, don't require
access to the pristine contents, so let's not limit them more than necessary.

* subversion/include/svn_wc.h
  (svn_wc_crawl_revisions5): Tweak documentation.

* subversion/libsvn_wc/deprecated.c
  (svn_wc_crawl_revisions5): Check the working copy settings and return an
   error only when restore_files is true.
