IIRC, the size parameter is 1/100 of a mil by default.

I recommend to use the unit parameter to reduce this kind of 
ambiguity. To achieve 7 mil width:
 ChangeSize(SelectedLines, 7, mil)

BTW, in section "actions" the manual still refers to 1/100 mil as the 
internal unit of pcb
	http://pcb.geda-project.org/pcb-cvs/pcb.html#Actions

It only mentions "mm" and "mil". In fact, pcb deals gracefully with 
the usual multiples, too. E.g. "m", "nm", "um", ...
No "ly", though ;-)
