No, it's a hint to the unexperienced user. We have disabled the input filter
for the power users, which might irritate the unexperienced user (see below).

The point is not "r4S{", but typos like "3cn" or "3,5" (the comma is common in
some countries) or a accidental key stroke which would be not possible with
an enabled filter etc.
Personally, I've found this hint useful several times, but maybe it is because
I am more blind when working.
