When should I edit posts?
Any time you feel you can make the post better, and are inclined to do so. Editing is encouraged!
Some common reasons to edit are:
to fix grammatical or spelling mistakes
to clarify the meaning of a post without changing it
to correct minor mistakes or add addendums / updates as the post ages
to add related resources or hyperlinks
Try to make the post substantively better when you edit, not just change a single character. Tiny, trivial edits are discouraged.
For me the change from "Here is the parted output:" to "Here is some more information as requested:" was too minor.
What followed "Here is the parted output:" was the output of sudo parted -l.
Following that there was more information but I don't think any reasonable person would have believed that the entire rest of the post was the output of the parted command.
For me and at least one other reviewer this change did not actually fix any problem with the question as I could see nothing wrong with the question as written. Edits are supposed to make the question (or answer) significantly better and for me at least this change was not significant.
If you look at this question on meta Is it acceptable for users to only gain reputation through a plethora of tiny edits?
You will see that reviewers don't always agree on what are and are not too minor
