Introduction of the git bisect terms function.
The user can set its own terms.
It will work exactly like before. The terms must be set
before the start.

`git bisect new <rev>`/`git bisect old <rev>...` after to add the
commits.
+Alternative terms: use your own terms
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the builtins terms bad/good and new/old do not satisfy you, you can
+set your own terms.
+
+------------------------------------------------
+git bisect terms term1 term2
+------------------------------------------------
+
+This command has to be used before a bisection has started.
+The term1 must be associated with the latest revisions and term2 with the
+ancestors of term1.
+
+Only the first bisection following the 'git bisect terms' will use the terms.
+If you mistyped one of the terms you can do again 'git bisect terms term1
+term2'.
