[svn-r19411] Purpose:
Add extra test cases for Bug1975 h5diff - support recursive comparison on group when specified as an object Description: Merged from hdf5 trunk (r19409) Additional tests for combination of group recursive and --follow-symlinks with multi-linked external links with several files (same name/strucure). Tested: jam, amani, heiwa
