Upstream commit: Date: Mon, 29 Apr 2019 19:13:37 +0500 expand: Fix trailing newlines processing in backquote expanding According to POSIX.1-2008 we should remove newlines only at the end of the substitution. Newlines-only substitions causes dash to remove newlines before beggining of the substitution. The following code: cat <<END 1 $(echo "") 2 END prints "1<newline>2" instead of expected "1<newline><newline>2". This patch fixes trailing newlines processing in backquote expanding.
