Updating batslib_count_lines to automatically detect trailing newlines and count them if present.
This works on the concept that a string has a trailing newline if it was intended -- e.g. via run --keep-empty-lines or similar.
Updating batslib_prefix and batslib_mark to accept --keep-empty-lines option to properly print empty lines and trailing newlines.
Updating batslib_print_kv_single_or_multi calls to batslib_prefix.
Will automatically detect trailing new lines (on a per-value basis).
If trailing newline is present, --keep-empty-lines will be passed to batslib_prefix.
This implements option 4 for batslib_count_lines and batslib_print_kv_single_or_multi, and option 2 for batslib_prefix and batslib_mark, as discussed in https://github.com/bats-core/bats-support/issues/11.
