git-grep configuration

git-grep-config.sh

# git-grep configuration – `man git-grep | cat && open https://git-scm.com/docs/git-grep` 

## turn off pager; print results directly to stdout instead:
git config --global pager.grep false

## enable line numbers by default:
git config --global grep.lineNumber true

## you can't set --ignore-case in git config.
## so instead, add the `-i` flag (short for`--ignore-case`)
## when searching:
git grep -i {query}

## use the --break flag to add a linebreak between files containing matches:
git grep -i --break {query}

## optionally, add your own convenient and nearly-familiar alias for git grep:
alias gg='git grep --ignore-case --break'
