Note for the others: `toggleMultiLine` doesn't seem to be used by Firebug extensions [1] [2]
@zendyani : I am fine with your renaming (the naming is better), but also note that we usually take care that it doesn't break Firefox addons relying on Firebug.
@janodvarko : Could we ask Mozilla to provide an MXR addons-search access to Jalil and Jakob?
