I won't.  I asked you what I didn't understand in what you said.
Answering the question is not being argumentative ;-)

What's relevant is not whether the script author was in the wrong or
in the right.

I do not agree with this reasoning at all.  Only if vast majority of
users incorrectly used the command and the option, we may need to
consider such a move as an exception, but not as a general rule.

But "stash list" example shows that "log --first-parent -m" without
"-p" in a script has a valid reason, and a change that hurts those
who correctly used a command and an option in a way they were
intended to do _is_ problematic.

Thanks.
