Sometimes, questions (or answers) contains a typo in the tag, title or description.
Is there a way to correct these mistakes without bumping the question? It could be a privilege, marking such edits as "Minor edit".
To prevent big changes from being done unnoticed, a maximum character limit of modifications could be introduced which is calculated since the last non-minor edit. Some characters (whitespace) could be ignored. Formatting like bold or italic could be ignored too in this character limit.
