Title edit plus minor body edit return 'too short' error
This Ask Ubuntu question has to do with Unity and panels, but its original title was "ronald plopper 999" (the OP's user name followed by 999).
So I edited the title and removed a superfluous newline in the text of the question itself, and got an error message stating that I changed too few characters. It could only have meant the characters of the message, ignoring the title.
I was forced to add a comment to the message to make my change happen. That seems foolish and should be changed.
Since the "editing help" encourages minor improvements, why am I forced to change at least n characters? Shouldn't spelling errors be corrected?
Would it have been better to ask this on Meta Ask Ubuntu?
Note: For search engines to succeed, you sometimes only need to correct a single character. Therefore changing a single character shouldn't be discouraged.
Note: In SE, SU, AU and Unix & Linux (maybe more?), a single character can make a significant difference. I don't think that the quality improvement can be measured or estimated by the number of characters changed.
Note: This question is not about how to properly change the cited example.
