In stretch, this was… questionable, but still valid:

In jessie, it recognised there was nothing to encode,
but still decided to wrap; unconventional but valid:
(jessie)$ printf '%s' 'Subject: UNNAMED PROJECT branch bnewplus updated.

In MirBSD, this worked well:
(mirbsd)$ perl -v | sed /./q
This is perl, v5.8.8 built for i386-mirbsd
(mirbsd)$ printf '%s' 'Subject: UNNAMED PROJECT branch bnewplus updated.

As I said in #879204, #879205, #787512, #881955, #787511,
#787513, #819155 (wow, is the list getting long), so far,
PHP seems to be the only ones getting it right (5 and 7.2):
(sid)$ printf '%s' 'Subject: UNNAMED PROJECT branch bnewplus updated.

This breaks my git post-receive-hook eMail sending script,
which uses the Perl way by default to encode the Subject
header (among others) as it’s the only one installed by
default, and people rightfully wish to avoid installing PHP.
