# Because the presence or absence of newlines is important to the operation of
# this function, and because $() strips trailing newlines, we'll encode things
# with "hexdump -c" before comparing them.

# ^P0 should be unquoted to \0 but there's no way to store that in an
# environment variable, so let's not even bother testing.

# Items without any quoted characters ar left unmolested.

# \n is quoted to ^Pn
