No, but it makes sense to write them as string constants. They are just
the strings "." and ".." padded with spaces to length 11, except they
are not actually strings since they are not NUL terminated. 11 is for
8+3 msdos short file names. These are not NUL terminated either, but
it should be easy to ignore the extra NUL given by the string constants.

The single quotes looking like commas indeed makes this hard to read.
