Good catch, thanks.

The "old style" version of the block in gnuradio-core in 3.6.5.1 works
correctly.  The "new style" version of the block in gr-filter in 3.6.5.1
has the sign change.  When all the old-style blocks were removed for
3.7, this of course left only the changed one.

Since it was Tom who did the conversion on that block, I'll wait until
he chimes in on whether his change was an accident or intentional.
