Teach 'git-grep(1)' a new option, '--column', to show the column
number of the first match on a non-context line. This makes it possible
to teach 'contrib/git-jump/git-jump' how to seek to the first matching
position of a grep match in your editor, and allows similar additional
scripting capabilities.

For example:

$ git grep -n --column foo | head -n3
.clang-format:51:14:# myFunction(foo, bar, baz);
.clang-format:64:7:# int foo();
.clang-format:75:8:# void foo()
