Comment 7 for bug 567547

Sorry, I sent the comment before finishing my explanation:

I think the vantages of this solution are:
- You can set more than one factoids with argument
- No unwanted setting of factoids
- No rule you have to learn
- Intuitive

Disadvantage: The following example does not work anymore:
pay $arg is <action> Pays to $who the amount of$1.
ibid: I'll remember that
pay $10.-
Possible resolution: do not check for $, but for $arg. So the rules for factoids with argument would be:
1. If the argument begins with $arg, its a setting
2. If not, its a getting.
