    Improve normalization with nested functions.
    
    normal() fails to fully normalize expressions where nested functions occur
    multiple times because replace_with_symbol() searches repl for an
    original expression but inserts into repl the substitued expression. Then
    the repeated search does not work and a new symbol is introduced.
    
    This patch fixes that by searching for the expression with the repl
    substituted instead of for the original expression.
