I don't see the mentioned change in the commit message. In particular: - As Eric pointed out in the previous round, the commit message misses the single most important point of justification: to determine whether '--option' or '--no-option' was specified at all. Explaining this would also make the examples unnecessary. - OPT_COUNTUP is used in several places, mostly indirecty, but the commit message doesn't explain that possible side-effects to these callers were considered and that they are not harmed by this change. > --- > Documentation/technical/api-parse-options.txt | 6 ++++-- > parse-options.c | 8 +++++++- > 2 files changed, 11 insertions(+), 3 deletions(-) A couple of new tests to t0040-parse-options.sh would be great to ensure that starting from a negative value works as advertised, i.e. at least that '--option' jumps to 1 and '--no-option' resets to 0. > diff --git a/Documentation/technical/api-parse-options.txt b/Documentation/technical/api-parse-options.txt > index 5f0757d..a908d8a 100644 > --- a/Documentation/technical/api-parse-options.txt > +++ b/Documentation/technical/api-parse-options.txt > @@ -144,8 +144,10 @@ There are some macros to easily define options: > > `OPT_COUNTUP(short, long, &int_var, description)`:: > Introduce a count-up option. > - `int_var` is incremented on each use of `--option`, and > - reset to zero with `--no-option`. > + If the `int_var` is negative and `--option` is absent, > + then it will retain its value.
