Documentation states "''One or more space-separated event types and optional namespaces, such as "click" or "keydown.myPlugin".''".

This is inconsistent with other methods of selecting items, e.g.

$('div p')

selects a <p> descendants of a <div>

whereas

$('div,p')

selects all <p> and all <div>. So comma = or, space = and.

The ''events'' parameter of ''.on()'' treats comma = ???, space = or.

If the ''events'' parameter of ''.on()'' used comma to delimit events, e.g.

$(something).on('change,keyup', .....

this would be a more consistent and logical way of specifying which events rather than the existing method of using space as a delimiter.
