I just edited a question which was missing a couple of {}
in its LaTeX markup. The effect was to make it hard to work out what was going on for people (such as, I presume, the OP) who don't know LaTeX or know it only at an even more superficial level than me.
However, when I tried to submit the edit I was told that it was too short: it had to be at least six characters, and it was only four.
My question therefore is: would it not be advisable to remove the minimum edit distance from Math.SE, given that there are circumstances in which even a one-character edit can have a dramatic effect on the legibility of the question?
(Or perhaps remove the minimum edit distance when the edit is to LaTeX markup)
