Should we change the flag too? It's confusing that the name of the flag does not
match the actual flag.

I was thinking that since command line flags are meant to be temporary, but they
might be saved by developers in scripts, shortcut properties, and shell history,
it is generally not worth changing them.  Indeed some of them have semantics
unrelated to their name.  Before asking if we should change it, maybe we should
first ask if we can remove it.

If you think this flag will need to stay around for a while, I would be happy to
rename it.

Personally, I would just change it. If you decide to not change the flag, I
would not change the kAltConstant.

Thank you for your recommendation.  Done.
