That makes sense (and I agree this is logically distinct from the
previous ones, which were about _showing_ commits, not generating them).

I wondered who is responsible for setting the "encoding" header in the
resulting object. It looks like we just call out to a separate "git
commit", feeding it some content we wrote out to a file. So before this
patch, I think we probably are writing out "encoding iso8859-1" or
whatever in the commit object, but actually outputting whatever the
original commit happened to have in it.

So your approach here is right: we just need to make sure what we write
out for git-commit to read back in is in i18n.commitEncoding.

Now what's going on here? This is a snippet of code we man to evaluate
later:

> +		test_line_count = 3 actual &&

I assume this is part of the same confusion that caused the
single-quotes in the earlier patch. You can just include those lines
inline in the quoted test snippet.
