Re: new snapshot available: grep-3.6.27-20b4

I also installed the attached minor improvements. I generated them while 
finding glitches in the code while writing a bigger patch set, which 
would cause grep to prefer signed types like idx_t over unsigned types 
like size_t, as signed types allow for better runtime checking. However, 
this bigger patch set isn't ready yet.
