A couple of time I've come across minor typos and Mathjax fixes I wanted to make to (other people's) questions which turn out to be too few characters to be passed by the Save Edit checking code.
Sometimes, IMO, especially with Mathjax, even a relatively minor tweak can help readability and clarity.
Does anyone feel the minimum character requirement is a bit restrictive ?
Could it be changed to a warning, rather than blocking small edits ?
Any ideas welcome.
