Improve sed portability
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.
