Since the type you use is (sexp :tag "Command"), you give relatively
little information to Custom about what it can look like (not that the
type is wrong, actually).

And yes, Custom should probably try to wrap lines somehow in such cases
(e.g. pretty-print the sexp).  During the wrapping, it could convert
the \n in strings into actual LF chars.
