ugrep v3.10.0

New option --tree to output directory trees of files for options -l \ 
(--files-with-matches), -L (--files-without-match) and -c (--count). Updated \ 
option --pretty to enable --tree when output is sent to a terminal. Disable with \ 
--no-tree to output a traditional grep flat list.
