[committed] gen-pass-instances.awk: Make print command clearer in handle_line

Hi,

this patch modifies the prefix and postfix expressions in handle_line 
gen-pass-instances.awk, such that the printf command now lists all the 
NEXT_PASS call arguments, and surrounds them with parentheses.

Committed to trunk as trivial.

Thanks,
- Tom
