No config exists for 'bugreport --diagnose' (and I don't think it would make sense to add one), so '--diagnose=none' would only be used to override another '--diagnose' specification in the same command/alias (e.g., 'git bugreport --diagnose=basic --diagnose=none').Ah, so --diagnose=none isn't valuable because --no-diagnose would be the better way to write the same thing. You would need to remove the PARSE_OPT_NONEG from your OPT_CALLBACK_F() to allow that (and then do the appropriate logic with the "unset" parameter).
I'm not sure I follow. I wasn't suggesting a difference in value between
'--no-diagnose' and '--diagnose=none'. My point was that, when there's an
option variant that "resets" the value to the default (like
'--no-autosquash', '--no-recurse-submodules', etc.), it usually *also*
corresponds to an overridable config setting ('rebase.autosquash',
'push.recurseSubmodules'). No such 'bugreport.diagnose' config exists (or,
IMO, should exist), so the need for a "reset to default" option seemed
weaker.
I used boolean options as my examples, but they aren't intended to imply a
meaningful difference between '--no-diagnose' amd '--diagnose=none'.
The reason to have these things is basically so users can create aliases (say 'git br' expands to 'git bugreport --diagnose=all', but they want to run 'git br --no-diagnose' to clear that --diagnose=all).
I considered that usage ("'--diagnose=none' would only be used to override
another '--diagnose' specification in the same command/alias"), but wasn't
sure how common it would be for this particular option. It sounds like you
can see it being useful, so I'll include '--diagnose=none' in the next
version.
