bug#10659: 24.0.93; (elisp) `scan-lists'

["Drew Adams" <drew.adams@oracle.com>]

These two sentences don't seem to fit together:
 
"If DEPTH is nonzero, parenthesis depth counting begins from that
value."
 
"Thus, a positive value for DEPTH means go out DEPTH levels of
parenthesis."
 
To make them fit I imagine that counting begins at a positive DEPTH and
decrements, not increments, until zero is reached.  That fits this, as
well:
 
"The only candidates for stopping are places where the depth in
parentheses becomes zero; `scan-lists' counts COUNT such places and then
stops."
 
Is that it?  Counting is *backward* from a positive DEPTH value *to
zero*?  If so, say so.  If not, clarify what does in fact happen.  As it
is now, the description is not clear.
