- Use "atf_check -x 'cmd1 | cmd2'" instead of "cmd1 | atf_check cmd2". The
two forms are idiomatically similar, but subtly different in the sense of
what program invokes the other, and there could be unwanted side effects
of the latter idiom dealing with forking, pipes, etc.
- Remove chmod and instead source coredump_phnum_restore_state.sh directly.
This avoids the need to check the result of the chmod call.
- Fix indentation in an if-block (4 column space indentation -> hard tab).
