<p>Fixing typos usually results in changing a character or very few.
When trying to fix such typos (on other people questions), I get a message that the change is too short.</p>

<p>I bypassed that problem by adding some more characters and deleting them in another edit but it seems like a hack.
It seems that I also cannot revert to the previous version so 3 rounds are needed.</p>

<p>How should typos be fixed?</p>
