Makes sense, but.

Now init_merge_options() takes care of setting o.renormalize, which
does exactly what the comment wanted to see happen.

Do we still need this file-scope static variable at all?

We no longer set value to option_renormalize in git_merge_config()
that is used only from cmd_merge().

And if somebody sets option_renormalize, then (and only then) we
override o.renormalize. One line before the precontext of this hunk
is a call to init_merge_options() that would have set o.renormalize
by reading merge.renormalize configuration. So there must be another
place where option_renormalize comes from other than that configuration
variable.
But I do not see the variable mentioned anywhere else in the
original The assignment to it in git_merge_config() you just got
rid of was the only one that used to assign to it.

OK.
IOW, wouldn't the attached be a no-op code clean-up on top?
