Pgbench variable substitution is performed when the script is run, not 
while the file is being processed for being split, which is when a lexer 
would be used. The situation is not the same with psql. The most it could 
do would be to keep track of what substitution are done in queries.

Possibly.  How much more effort would be involved compared to the quick 
patch I did, I wonder:-)
