Of course it depends on who you are. It's not Ok for somebody like you,
who is known to be competent, and certainly it is not Ok to do it on a
command that you know you care more about than I do.
I've neglected builtin-mv.c since its introduction, mostly because I never
say "git mv" myself (in other words, I haven't cared very much how broken
it was. For one thing, its indentation style is peculiar and is hard to
read and maintain).

Yes, I would agree this is a reasonable thing to support. Something like
this patch, perhaps.
