Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.

The prefix_path_gently() function currently applies real_path to
everything if given an absolute path, dereferencing symlinks both
outside and inside the work tree.
This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink
attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.
In order to manipulate symlinks in the work tree using absolute paths,
symlinks should only be dereferenced outside the work tree.
Modify the prefix_path_gently() to first normalize the path in order to
make sure path levels are separated by '/', then pass the result to
'abspath_part_inside_repo' to find the part inside the work tree
(without dereferencing any symlinks inside the work tree).
For absolute paths, prefix_path_gently() did not, nor does now do, any
actual prefixing, hence the result from abspath_part_in_repo() is
returned as-is.
Fixes t0060-82 and t3004-5.

When symlinks in the working tree are manipulated using the absolute
path, git dereferences them, and tries to manipulate the link target
instead.
This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink
attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.
This is a regression introduced by 18e051a:
setup: translate symlinks in filename when using absolute paths
(which did not take symlinks inside the work tree into consideration).
Add a known-breakage test using the ls-files function, checking both if
the symlink leads to a target in the same directory, and a target in the
above directory.

Use the i18n-specific test functions in test scripts for parseopt tests.
This issue was was introduced in v1.7.10.1-488-g54e6d:
54e6d i18n: parseopt: lookup help and argument translations when showing usage
and been broken under GETTEXT_POISON=YesPlease since.

Part of a campaign to avoid git <command> -h being distracted by
access to the repository. A caller hoping to use "git ls-files"
with an alternate index as part of a repair operation may well use
"git ls-files -h" to show usage while planning it out.
[jn: with rewritten log message and tests]
