Package: dash
Version: 0.5.7-4+b1
Severity: normal
Dear Maintainer,
In multi-line string literals, a line which starts with a $()-style
subshell which outputs an empty string will have its trailing newline
stripped. For example, this code:
echo "
$(echo '') hello
$(echo '') world"
will output " hello world", when other shells I've tried
(zsh, bash, ksh) all output:
"
hello
world"
I haven't looked at what posix says about this particular issue,
but the behavior of all the other shells looks way more sensible in my
opinion. If they're actually wrong and dash implements posix correctly,
feel free to ignore this issue.
