Subject: [PATCH] Moved tests for commit -o option to own test class

We test the -o option of the commit command very accurate by
writing tests for each line of a decision table. In order to
still be able to point new jgit users to the CommitAndLogCommandTest
to find out how to use log() and commit() I factored out these 1200
lines of very specific tests into their own class.

 /**
  * Testing the git commit and log commands
- *
- * Testing the 'commit only' option:
- *
- * I. A single file (f1.txt) specified as part of the --only/ -o option can have
- * one of the following (14) states:

- * </pre>
- *
- * II. Scenarios that do not end with a successful commit (1, 2, 6, 7, 12) have
- * to be tested with a second file (f2.txt) specified that would lead to a
- * successful commit, if it were executed separately (e.g. scenario 14).
- *
- * <pre>

- *
- * III. All scenarios (1-14, I-II) have to be tested with different repository
- * states, to check that the --only/ -o option does not change existing content
- * (HEAD and DirCache). The following states for a file (f3.txt) not specified
- * shall be tested:
- *
- * <pre>
- *       | HEAD  DirCache
- * --------------------

- *  *_d  |  c       -
- * --------------------
- *  *_e  |  c       c'
- * </pre>

+ *
+ * <pre>
+ *        |                          | expected result
+ * ---------------------------------------------------------------------
+ *        | HEAD  DirCache  Worktree | HEAD  DirCache
+ * ---------------------------------------------------------------------
+ *  f1_1  |  -       -       c       |                => e: path unknown
+ *  f1_2  |  -       c       -       |                => no changes

+ *  f1_4  |  -       c       c       |  c       c
+ *  f1_5  |  c       c       -       |  -       -
+ *  f1_6  |  c       -       c       |                => no changes
+ *  f1_7  |  c       c       c       |                => no changes

+ * f1_11  |  c       c       c'      |  c'      c'
+ * f1_12  |  c       c'      c       |                => no changes

+ * ---------------------------------------------------------------------
+ * f1_14  |  c       c'      c''     |  c''     c''
+ * </pre>
+ *
+ * II. Scenarios that do not end with a successful commit (1, 2, 6, 7, 12) have
+ * to be tested with a second file (f2.txt) specified that would lead to a
+ * successful commit, if it were executed separately (e.g. scenario 14).
+ *
+ * <pre>
+ *              |                          | expected result
+ * ---------------------------------------------------------------------------
+ *              | HEAD  DirCache  Worktree | HEAD  DirCache
+ * ---------------------------------------------------------------------------
+ *  f1_1_f2_14  |  -       -       c       |                => e: path unknown
+ *  f1_2_f2_14  |  -       c       -       |  -       -
+ *  f1_6_f2_14  |  c       -       c       |  c       c
+ *  f1_7_f2_14  |  c       c       c       |  c       c
+ * ---------------------------------------------------------------------------
+ * f1_12_f2_14  |  c       c'      c       |  c       c
+ * </pre>
+ *
+ * III. All scenarios (1-14, I-II) have to be tested with different repository
+ * states, to check that the --only/ -o option does not change existing content
+ * (HEAD and DirCache). The following states for a file (f3.txt) not specified
+ * shall be tested:
+ *
+ * <pre>
+ *       | HEAD  DirCache
+ * --------------------
+ *  *_a  |  -       -
+ *  *_b  |  -       c
+ *  *_c  |  c       c
+ *  *_d  |  c       -
+ * --------------------
+ *  *_e  |  c       c'
+ * </pre>
