This is definitely the right direction, but I was a little surprised it
worked at all on other shells! Both bash and dash end the here-doc at
the end of the input (in this case the end of the eval string). They end
up sucking the EOF and the follow-on commands into the here-doc, and the
test literally does nothing except the call to cat.
Bash does print a warning in this case. It would be nice to upgrade it
to an error (so at least bash users could easily detect the buggy
script), but I don't see any way to do so. I guess running with mksh is
a good substitute. :)
However, in most such instances of this problem, the shell will notice
and barf, because it syntactically expects more on the next line:
$ sh -c '
cat >foo <<EOF &&
whatever
EOF
do_something
'
sh: 6: Syntax error: end of file unexpected
So the problem in this instance is that the here-doc marker is wrong
_and_ the test accidentally broke the &&-chaining:
> test_expect_success '--no-standard-notes' '
> - cat >expect-commits <<EOF
> + cat >expect-commits <<-EOF
The ideal line here would be:
cat >expect-commits <<-EOF &&
-Peff
