ugrep: updated to 3.12.3

ugrep v3.12.3

Speed improvements to further speed up common search patterns. Improved man \ 
page. The ug and ug+ commands now enable --pretty by default (that is, if a \ 
.ugrep configuration file does not override it with no-pretty). Fixed a \ 
potential pattern match issue in the new v3.12 optimizations.
