Right. We have NULLs in the fifth and the second-to-last positions, and
we use PARSE_OPT_NOARG. By switching to OPT_SET_INT_F we get those for
free.
Do we want to keep "(s)" instead of "s", just to be safe? And same for
"(v)", "(p)". Macro expansion always makes me paranoid.

I found `-w` and `--word-diff` useful. You actually change the N_("...")
for `--no-keep-cr` here: [-independent of am.keepcr-]{+for mbox format+}
Copy-paste mistake?
Other than that, `--word-diff` has a very structured appearance and
nothing stood out. The ordering is different (f goes at the end in the
post-image), which makes the diff busier than it would have had to be.
(That's obviously nothing this patch can do anything about.)
