No need to resend but the above context line somehow got line-wrapped.

This is not a new (as linkgit:git[1] also has it) but "override" is
a white lie, and may invite nitpickers.  The -c var=val given from
the "git" command line is merely tacked at the end of the search
order, so it would "override" when the variable is used as a
single-valued variable, but when it is used as multi-valued one, it
does not.

That might be something we want to fix up further in later patches;
the change we see in this patch is good regardless.

Thanks.
