Fix plpgsql named-cursor-parameter feature for variable name conflicts.
The parser got confused if a cursor parameter had the same name as
a plpgsql variable. Reported and diagnosed by Yeb Havinga, though
this isn't exactly his proposed fix.
Also, some mostly-but-not-entirely-cosmetic adjustments to the original
named-cursor-parameter patch, for code readability and better error
diagnostics.
