Yes, $BASH_SOMETHING is just used to make it easier to see that the 
following code (probably a bashism) is only executed after checking the 
shell is actually bash. That and the other FP are the most common ones, yet 
not that easy to fix (the latter, of course, the former is not a FP.)

Could you please send me by email the files with false negatives? those are 
very likely bugs in checkbashisms' quotes handling code.

Thanks.
