58960978 and 99780b0a added tests which demonstrated bugs (crashes) in
range-set and line-log when handed empty ranges specified via "log
-LX:file" where X is one greater than the last line of the file. After
these tests were added, it was realized that the ability to specify an
empty range is a loophole due to a bug in -L bounds checking. That bug
is slated to be fixed in a subsequent patch.
Unfortunately, the closure of this loophole makes it impossible to
continue checking range-set and line-log behavior with regard to empty
ranges since there is no other way to specify empty ranges via the
command-line. APIs of both facilities are private (file static) so
there likewise is no way to test their behaviors programmatically.
Consequently, retire these two tests.

A bounds checking bug allows the X in -LX to extend one line past the

Since inception, -LX,Y has correctly reported an out-of-range error when
Y is beyond end of file, however, X was not checked, and an out-of-range
X would cause a crash. 92f9e273 (blame: prevent a segv when -L given
start > EOF; 2010-02-08) attempted to rectify this shortcoming but has
its own off-by-one error which allows X to extend one line past end of
file. For example, given a file with 5 lines:
git blame -L5 foo # OK, blames line 5
git blame -L6 foo # accepted, no error, no output, huh?
git blame -L7 foo # error "fatal: file foo has only 5 lines"
Fix this bug.
In order to avoid regressing "blame foo" when foo is an empty file, the
fix is slightly more complicated than changing '<' to '<='.

Add boundary case tests, with and without -L, for empty file; file with
one partial line; file with one full line.
The empty file test without -L is of particular interest. Historically,
this case has been supported (empty blame output) and this test protects
against regression by a subsequent patch fixing an off-by-one bug which
incorrectly accepts -LX where X is one past end-of-file.

t8001, t8002: fix "blame -L :literal" test on NetBSD
Sub-test 42 of t8001 and t8002 ("blame -L :literal") fails on NetBSD
with the following verbose output:
git annotate -L:main hello.c
Author F (expected 4, attributed 3) bad
Author G (expected 1, attributed 1) good
This is not caused by different behaviour of git blame or annotate on
that platform, but by different test input, in turn caused by a sed
command that forgets to add a newline on NetBSD. Here's the diff of the
commit that adds "goodbye" to hello.c, for Linux:
It also adds an extra TAB, but it is missing the newline character
after the semicolon.
The following patch gets rid of the extra TAB at the beginning, but
more importantly adds the missing newline at the end in a (hopefully)
portable way, mentioned in http://sed.sourceforge.net/sedfaq4.html.
The diff becomes this, on both Linux and NetBSD:
t3900: test rejecting log message with NULs correctly
It is not like that our longer term desire is to someday start
accept log messages with NULs in them, so it is wrong to mark a test
that demonstrates "git commit" that correctly fails given such an
input as "expect-failure". "git commit" should fail today, and it
should fail the same way in the future given a message with NUL in it.
The test file that the UTF-16 rejection test looks for is missing, but this went
unnoticed because the test is expected to fail anyway; as a consequence, the
test fails because the file containing the commit message is missing, and not
because the test file contains a NUL byte. Fix this by including a sample text
file containing a commit message encoded in UTF-16.

commit-slab.h: Fix memory allocation and addressing
The slab initialization code includes the calculation of the
slab 'elem_size', which is in turn used to determine the size
(capacity) of the slab. Each element of the slab represents an
array, of length 'stride', of 'elemtype'. (Note that it may be
clearer if the define_commit_slab macro parameter was called
'basetype' rather than 'elemtype'). However, the 'elem_size'
calculation incorrectly uses 'sizeof(struct slabname)' in the
expression, rather than 'sizeof(elemtype)'.
Within the slab access routine, <slabname>_at(), the given commit
'index' is transformed into an (slab#, slot#) pair used to address
the required element (a pointer to the first element of the array
of 'elemtype' associated with that commit). The current code to
calculate these address coordinates multiplies the commit index
by the 'stride' which, at least for the slab#, produces the wrong
result. Using the commit index directly, without scaling by the
'stride', produces the correct 'logical' address.
Also, when allocating a new slab, the size of the allocation only
allows for a slab containing elements of single element arrays of
'elemtype'. This should allow for elements of an array of length
'stride' of 'elemtype'. In order to fix this, we need to change
the element size parameter to xcalloc() by multiplying the current
element size (sizeof(**s->slab)) by the s->stride.
Having changed the calculation of the slot#, we now need to convert
the logical 'nth_slot', by scaling with s->stride, into the correct
physical address.

commit: tweak empty cherry pick advice for sequencer
When we refuse to make an empty commit, we check whether we
are in a cherry-pick in order to give better advice on how
to proceed. We instruct the user to repeat the commit with
"--allow-empty" to force the commit, or to use "git reset"
to skip it and abort the cherry-pick.
In the case of a single cherry-pick, the distinction between
skipping and aborting is not important, as there is no more
work to be done afterwards. When we are using the sequencer
to cherry pick a series of commits, though, the instruction
is confusing: does it skip this commit, or does it abort the
rest of the cherry-pick?
It does skip, after which the user can continue the
cherry-pick. This is the right thing to be advising the user
to do, but let's make it more clear what will happen, both
by using the word "skip", and by mentioning that the rest of
the sequence can be continued via "cherry-pick --continue"
(whether we skip or take the commit).

During processing, various range-set utility functions break the

sort_and_merge_range_set(), however, neglects to fold out empty
