When editing posts on StackOverflow, the following message appears:
We welcome all constructive edits, but please make them substantial. Avoid trivial, tiny one-letter edits unless absolutely necessary.
How does that advice apply to Spanish.SE? Are small (even one-character) edits to fix grammar, spelling, or punctuation recommended? Or should they be avoided to stop lots of cleanup from forcing questions or answers into Community Wiki mode (or for other reasons)?
