I have noticed that "make test" fails without any explanations when the
"merge" utility is missing. I don't think tests should be silent in
case of failure.
It turned out that the particular test was using "exit" to interrupt the
test in case of an error. This caused the whole test script to exit.
No further tests would be run even if "--immediate" wasn't specified.
No error message was printed.
This patch does following:
All instances of "exit", "exit 1" and "(exit 1)" in tests have been
replaced with "return 1". In fact, "(exit 1)" had no effect.
File descriptor 5 is duplicated from file descriptor 1. This is needed
to print important error messages from tests.
New function test_run_() has been introduced. Any "return" in the test
would merely cause that function to return without skipping calls to
test_failure_() and test_ok_(). The new function also traps "exit" and
treats it like a fatal error (in case somebody reintroduces "exit" in
the tests).
test_expect_failure() and test_expect_success() check both the result of
eval and the return value of test_run_(). If the later is not 0, it's
always a failure because it indicates the the test didn't complete.

This adds more tests for --emu23. One is to show how it can
carry forward more local changes than the straightforward
two-way fast forward, and another is to show the recent
overeager optimization of directory/file conflict check broke
things, which will be fixed in the next commit.

This is in preparation for "2-way fast-forward emulated with
3-way mechanism" series. It does not change what the tests for
pure 2-way do. It only changes how it tests things, to make
reviewing of differences of the two tests easier in later steps.

This implements the "never lose the current cache information or
the work tree state, but favor a successful merge over merge
failure" principle in the fast-forward two-tree merge operation.
It comes with a set of tests to cover all the cases described in
the case matrix found in the new documentation.
