/*
 * Perl-style 'chomp', for a line we just read with fgetline.
 *
 * Unlike Perl chomp, however, we're deliberately forgiving of strange
 * line-ending conventions.
 *
 * Also we forgive NULL on input, so you can just write 'line =
 * chomp(fgetline(fp));' and not bother checking for NULL until
 * afterwards.
