on this answer http://unix.stackexchange.com/posts/283528/revisions I added example code to actually accomplish what was in the answer. It said use tool XYZ and I showed how to use it specifically as an answer to the question (as in, XYZ parameters...).

My edit was later reverted back to the original answer.

Two questions here:

1. when is it okay to add examples/code to an existing answer? I didn't want to duplicate an answer just with some more examples.
2. was it okay to revert the answer back to the original that did not include examples and, at least in my opinion, is slightly less useful to answer-seekers?
