Since 99fb6e04cb (pack-objects: convert to use parse_options(),
2012-02-01) git pack-objects has accepted the option --no-quiet, but it
does the same as --quiet. That's because it's defined using OPT_SET_INT
with a value of 0, which sets 0 when negated, too.
Make --no-quiet equivalent to --progress and ignore it if --all-progress

Since 2c33f75754 (Teach git-describe --exact-match to avoid expensive
tag searches, 2008-02-24) git describe accepts --no-exact-match, but it
does the same as --exact-match, an alias for --candidates=0. That's
because it's defined using OPT_SET_INT with a value of 0, which sets 0

Let --no-exact-match set the number of candidates to the default value
instead. Users that need a more specific lack of exactitude can specify
their preferred value using --candidates, as before.
The "--no-exact-match" option was not covered in the tests, so let's
add a few. Also add a case where --exact-match option is used on a
commit that cannot be described without distance from tags and make

As mentioned in the thread starting at [1], trace2 counters should be
used to count events instead of ad-hoc static variables.
Convert the two fsync static variables to trace2 counters, reducing the
coupling between wrapper.c and the trace2 subsystem. Adjust t/t5351 to
match the trace2 counter output format.
The counters are not per-thread because the ones being replaced also
were not.

"git reset --no-mixed" behaved exactly like "git reset --mixed",
which was nonsense.
If there were only two kinds, e.g. "mixed" vs "separate", it might
have made sense to make "git reset --no-mixed" behave identically to
"git reset --separate" and vice-versa, but because we have many
types of reset, let's just forbid "--no-mixed" and negated form of
other types.

"git show-branch --no-topo-order" behaved exactly the same way as
"git show-branch --topo-order" did, which was nonsense. This was
because we choose between topo- and date- by setting a variable to
either REV_SORT_IN_GRAPH_ORDER or REV_SORT_BY_COMMIT_DATE with
OPT_SET_INT() and REV_SORT_IN_GRAPH_ORDER happens to be 0. The
OPT_SET_INT() macro assigns 0 to the target variable in respose to
the negated form of its option.
"--no-date-order" by luck behaves identically to "--topo-order"
exactly for the same reason, and it sort-of makes sense right now,
but the "sort-of makes sense" will quickly break down once we add a
third way to sort. Not-A may be B when there are only two choices
between A and B, but once your choices become among A, B, and C,
not-A does not mean B.
Just mark these two ordering options to reject negation, and add a
test, which was missing. "git show-branch --no-reflog" is also
unnegatable, so throw in a test for that while we are at it.

"git show-branch --no-sparse" behaved exactly the same way as "git
show-branch --sparse", which did not make any sense. This was
because it used a variable "dense" initialized to 1 by default to
give "non sparse" behaviour, and OPT_SET_INT() to set the varilable
to 0 in response to the "--sparse" option. Unfortunately,
OPT_SET_INT() sets 0 to the given variable when the option is
negated.
Flip the polarity of the variable "dense" by renaming it to "sparse"
and initializing it to 0, and have OPT_SET_INT() set the variable to
1 when "--sparse" is given. This way, "--no-sparse" would set 0 to
the variable and would give us the "dense" behaviour.

As the command line parser for "git branch --all" forgets to use
PARSE_OPT_NONEG, it accepted "git branch --no-all", and then passed
a nonsense value to the underlying machinery, leading to a fatal
error "filter_refs: invalid type". The "--remotes" option had
exactly the same issue.

Command line options "--keep-cr" and its negation trigger
OPT_SET_INT_F(PARSE_OPT_NONEG) to set a variable to 1 and 0
respectively. Using OPT_SET_INT() to implement the positive variant
that sets the variable to 1 without specifying PARSE_OPT_NONEG gives
us the negative variant to set it to 0 for free.
