The list of software that supports that "convention" is, eh,
respectable. Is it really a "convention" yet, or yet another thing
the user needs to worry about?

Our convention often calls for CONFIG_VAR=false to mean "I do not
want to see what CONFIG_VAR wants to do done", i.e.
NO_COLOR=false git show
would show colored output if there is no other settings. But this
code contradicts the convention, deliberately because that is what
no-color.org wants. Makes me wonder if that convention is worth
following in the first place.

According to no-color.org's FAQ #2, NO_COLOR should affect only the
"default" behaviour, and should stay back if there is an explicit
end-user configuration (or command line override). And this helper
function is called only from want_color() when their is no such
higher precedence setting, which is in line with the recommendation.
Which is good.
