[Collin Funk]

This patch just fixes two simple newline differences in test
directories.

Also, something that may be worth keeping in mind as we try to match
the output of gnulib-tool.py and gnulib-tool.sh, I find it easier to
follow this:

    emit += 'AM_PROG_CC_C_O\n'
    emit += '\n'

rather than this:

    emit += 'AM_PROG_CC_C_O\n\n'

Since it more closely resembles the 'echo' invocations. Nothing worth
losing sleep over, but worth keeping in mind.
