The behaviour of "sed" on an incomplete line is unspecified by POSIX, and
On Solaris it apparently fails to process input that doesn't end in a LF.
Consequently constructs like
re=$(printf '%s' foo | sed -e 's/bar/BAR/g' $)
cause re to be set to the empty string. Such a construct is used in
git-submodule.sh.
Because the LF at the end of command output are stripped away by the
command substitution, it is a safe and sane change to add a LF at the end
of the printf format specifier.
