When using ModelForms with Models that include ManyToManyField's there's a default help_text message:
"Hold down "Control", or "Command" on a Mac, to select more than one."
If you use a different widget for fields of this type, such as CheckboxSelectMultiple, the help_text message makes no sense.
The way it's currently implemented the message is always appended to what is passed.
The attached patch changes this such that the message is only displayed if the empty string is passed (which is also the default by omission).
