I am wondering why edits are required to be at least 6 characters.
As an example, someone answered the question How to calculate the integral of a Legendre polynomial excellently but for a typo, which requires just one character change (it should say "Choosing $u=v=\alpha$" rather than "Choosing $u=v=2\alpha$"). When I tried to edit the answer, I'm told that edits must be at least 6 characters long. I suppose there must be a reason for this, but it seems totally unnecessary, particularly for examples like this.
Is there a way of getting around this without doing another superfluous edit?
