[ELPA Syncer]

commit d990a98ac10adf5b04b76aa71a25afc5c8899744

    Avoid printing double lines in GitHub Actions
    
    The "terminal" used in github action does not support the use of
    carriage return '\r' to move back to column zero and overwrite the
    line.  Carriage return will instead move to the next line.
    
    The consequence for the buttercup batch reporer was that each spec
    description was printed twice, once without color before the spec was
    run and once with color once the spec had run and the result was
    known.  Reuse the same mechanism as for specs with descriptions
    containing newlines, don't print the spec description before running
    it unless color is disabled.
    
    Fixes #181.
