ugrep: updated to 3.7.7

ugrep v3.7.7
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 colorization of option -v when used with \ 
context options -A, -B and -C. Fixed option -r when combined with argument - \ 
(read standard input), which does both, like GNU grep. Updated --stats reporting \ 
and other minor improvements.
