The `while' loop jumps to the beginning of the current "assignment 
expression".

`js--skip-terms-backward' is similar because it skips to the beginning 
of the call chain. It's more narrow, though (the other function also 
jumps over binary operators).

Anyway, I'm not so sure there's much value in unifying the 
implementations anymore.
