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).

range-set invariants are: ranges must be (1) non-empty, (2) disjoint,

line_log_data_insert() breaks the non-empty invariant under the
following conditions: the incoming range is empty and the pathname
attached to the range has not yet been encountered. In this case,
line_log_data_insert() assigns the empty range to a new line_log_data
record without taking any action to ensure that the empty range is
eventually folded out. Subsequent range-set functions crash or throw an

range-set invariants are: ranges must be (1) non-empty, (2) disjoint,

During processing, various range-set utility functions break the
invariants (for instance, by adding empty ranges), with the
expectation that a finalizing sort_and_merge_range_set() will restore
sanity.
sort_and_merge_range_set(), however, neglects to fold out empty
ranges, thus it fails to satisfy the non-empty constraint. Subsequent

open_istream: remove unneeded check for null pointer
'st' is allocated via xmalloc a few lines before and passed to

The xmalloc function is written in a way that either 'st' is allocated

passed by reference and not a pointer of a pointer.

The purpose of git-contacts is to determine a list of people who might

git-send-email's --cc-cmd argument or the computed list might be used to
ask for comments on a proposed change. As such, it is important to
report up-to-date email addresses in the computed list rather than
potentially outdated ones recorded with commits. Apply git's mailmap

This script lists people that might be interested in a patch by going
back through the history for each patch hunk, and finding people that
reviewed, acknowledged, signed, authored, or were Cc:'d on the code the
patch is modifying.
It does this by running git-blame incrementally on each hunk and then
parsing the commit message. After gathering all participants, it
determines each person's relevance by considering how many commits
mentioned that person compared with the total number of commits under
consideration. The final output consists only of participants who pass a
minimum threshold of participation.
Several conditions controlling a person's significance are currently
hard-coded, such as minimum participation level, blame date-limiting,
and -C level for detecting moved and copied lines. In the future, these
conditions may become configurable.
For example:
% git contacts 0001-remote-hg-trivial-cleanups.patch

since e6c111b4 we return error, and it is misleading.
As this variable tells us which trees in t[] array were used in the
callback function, so that this caller can know the entries in which
of the trees need advancing, "trees_used" is a better name.
Also the assignment to 0 was removed at the start of the function as
well after the "if (interesting)" block. Those are unneeded as that
variable is set to the callback return value any time we enter the
