Whenever you start entering numbers like ".1" or "-1" for transform
operators or any number input in the 3D view, error messages would
end up in the terminal when the first character is entered:

File "<string>", line 1
    .
    ^
SyntaxError: unexpected EOF while parsing

While this isn't at all a blocking issue, it can get a bit annoying,
so maybe it makes sense to remove these messages for these two common
cases.
