test-rename-merge2: make selected output less arbitrary
It's unclear why everything from the first 'updating:' line should be
ignored. The arbitrariness makes it confusing that changing the code
so e.g. the 'getting 8/f' line is printed later makes it disappear
completely from the ouput. The list of 'preserving x for resolve of y'
seems convered by the subsequent for loop in the test case. Perhaps
it's only copies that are of interests, so let's keep only that part.
#!/usr/bin/env python
import errno, os, sys
for f in sys.argv[1:]:
try:
print f, '->', os.readlink(f)
except OSError as err:
if err.errno != errno.EINVAL:
raise
print f, 'not a symlink'
sys.exit(0)
