[committed] gen-pass-instances.awk: Rename prefix_len var to len_of_prefix in handle_line

[Tom de Vries]

Hi,

this patch renames variable prefix_len to len_of_prefix in handle_line 
in gen-pass-instances.awk, to match the naming convention in the rest of 
the function.

Committed to trunk as trivial.

Thanks,
- Tom
