# the accidental cr.cr.lf sequence.) If some lines end lf, and others as
# cr.lf, the file is presumed binary. If the cr character appears anywhere
# except prefixed to an lf, the file is presumed binary. If there is no
# change in the resulting file size, or the file is binary, the conversion
# is discarded.
