Comment 23 for bug 159066

@ all:
I think indicate a partial refuel in the following manner (using : or ~ instead of =):

- partial will be d=5555 v:5.32 or v~5.32
- full still be d=5555 v=45.03

I prefer to avoid force the user to seize pf= in every case, just simpler to change the actual rule.

Let me know what you think and prefer between : or ~ or propose something else.
