ugrep: updated to 3.7.9

ugrep v3.7.9
Additional --stats results with total lines searched and matched, and time \ 
elapsed. New complementary options --min-depth, --max-depth, --min-line and \ 
--max-line which are added for consistency with the updated options --min-count \ 
and --max-count. Updated the --min-count option, which can now be combined with \ 
any other option except with -v (--invert-match). Updated option -K (--range) to \ 
take a MAX argument instead of a FIRST argument for consistency with other \ 
min/max options. Recursive searching sysfd, such as /proc and /sys, no longer \ 
blocks on special files/devices. Fixed inconsistent colorization with option -v \ 
when used with context options -A, -B and -C. Fixed option -r when combined with \ 
file argument - (read standard input), which does both, like GNU grep. Other \ 
minor improvements.
