Thanks, I like the direction here. Definitely it would need
documentation, but also tests (probably in t4013 alongside the ones my
series added; in fact you'd probably need to adjust my tests for the
non-optional argument).

Should this be revs->ignore_merges = 0?

I think Junio's suggestion to push these out to a separate patch is a
good one.
It's unfortunate that we have to duplicate all of the various options
that get set (from the "--cc", etc, blocks). But I think the boilerplate
for pushing it into a helper would make it even harder to read.

A few nits:
- we usually don't have a period at the end of our error messages
- this should probably be marked for translation, i.e.,
die(_("translated message"), optarg)
- I think other similar messages are more like:
unknown value for --diff-merges: %s

I thought at first that the --no- form would be handled by
parse_long_opt() via the parseopt code, but it is not using parseopt at
all. :) So it is correct to keep this.
