The additions to each file just have to be consistent with what's 
already there. The presently discussed patch, wasn't.

Speaking of personal preference, however, I'd rather using the `mouse' 
group didn't work, in the absence of a defgroup somewhere.

How would removing a defcustom, or merely adding one, lead to a bug?

The new defcustom might have :group unspecified, and if there's no 
defgroup in the current file, it would become a problem, but that's 
unrelated to any defcustom's already present in the file.
