This patch fixes some formatting and code clarity issues I've tripped 
over in the past few months.

duplicate_decls has some function- and var- specific behaviour that was 
confusingly commented, and, for the var case mixed the checking for var 
with checking for the flag to copy.

process_outer_var_ref had some unnecessary line-breaks and block scopes.

explain_implicit_non_constexpr had some unnecessary repetitiveness.

Applying to trunk.
