Imperative mood (and dropping unnecessary "builds upon previous"):

    Teach 'git-grep(1)' a new option '--column-number' which shows the
    column number of the first match on a non-context line.

Show 10 quoted lines

As mentioned in my review of patch 2, document the configuration variables in the patch which introduces them.

Show 16 quoted lines

I realize that several existing tests in this script are already guilty of this sin, but please give each new test a distinct title reflective of what it is actually testing in order to make it easier to correlate failed test output with the actual test code.
