ugrep: updated to 3.12.6

ugrep v3.12.6

New option -S (--dereference-files) to follow symbolic links only to files, not \ 
to directories, when using option -r for recursive search. Updated default \ 
recursive search to strictly perform -r without following any symbolic links \ 
(use -S to search symlinked files). New option --index for fast index-based \ 
search with the new ugrep-indexer tool. The ugrep-indexer tool is released on \ 
GitHub as a separate open source project at \ 
https://github.com/Genivia/ugrep-indexer which will become part of ugrep later \ 
after more feedback is received for this new feature.
