Avoid a bug in dash that's been fixed ever since its
ec2c84d ("[PARSER] Fix clobbering of checkkwd", 2011-03-15)[1] first
released with dash v0.5.7 in July 2011. This failing test was
introduced in 5f9674243d ("config: add --expiry-date", 2017-11-18).

This fixes 1/2 tests failing on Debian Lenny & Squeeze. The other

Do I understand this "1/2" right?  There are two tests failing on
Lenny and Squeeze, and this fixes one of those bugs?

Yeah, so there's one bug left now, which I haven't tracked down.

failure is due to 1b42f45255 ("git-svn: apply "svn.pathnameencoding"
before URL encoding", 2016-02-09).

The dash bug is triggered by this test because the heredoc contains a
command embedded in "$()" with a "{}" block coming right after
it. Refactoring the "$()" to e.g. be a variable that was set earlier
will also work around it, but let's instead break up the "EOF" and the
"{}".

An earlier version of this patch[2] mitigated the issue by breaking
the "$()" out of the "{}" block, that worked, but just because it
broke up the "EOF" and "{}" block. Putting e.g. "echo &&" between the
two would also work.

Could you please link directly to the commit fixing that issue?

Should have done that, but I'll hold off on a re-roll for such a minor
cosmetic issue since I see Junio's merged it down to "next" already. The
dash.git hash is noted in the commit message, so it's not a practical
problem to find the commit, but yeah, would be nice if were a clickable
link.
