I have undone the auxiliary edits to git-add.txt.

I am sorry about that. The instructions in SubmittingPatches clearly
mentioned that this will happen, but still I was not careful enough.

Hopefully this one should not be broken.

Subject: [PATCH v2] docs: improve discoverability of exclude pathspec

The ability to exclude paths with a negative pathspec is not mentioned
in the man pages for git grep and other commands where it might be
useful.

Add an example and a pointer to the pathspec glossary entry in the man
page for git grep to help the user to discover this ability.

Add similar pointers from the git-add and git-status man pages.

Additionally,

- Add a test for the behaviour when multiple exclusions are present.
- Add a test for the ^ alias.
- Improve name of existing test.
- Improve grammar in glossary description of the exclude pathspec.
