Re: [PATCH] Add missing test file for UTF-16.

Duy Nguyen [off-list ref] writes:

The intention was "UTF-16 is not supported yet but we want to". But I
don't think we (at least I) will put any effort on that front to allow
NUL in commit message, so the patch, as in "we do not support UTF-16",
is fine.

Agreed.  Here is what I queued.

Subject: [PATCH] t3900: test rejecting log message with NULs correctly

It is not like that our longer term desire is to someday start
accepting log messages with NULs in them, so it is wrong to mark a test
that demonstrates "git commit" that correctly fails given such an
input as "expect-failure".  "git commit" should fail today, and it
should fail the same way in the future given a message with NUL in it.
