Because the Excel programmers are sloppy. A valid SYLK file begins
with `ID;' or `ID' alone on a line.
Sometimes Excel incorrectly says `SYLK: file format is not valid.'.
When you try to open a text file that begins with, say, `ID' and a tab,
it could not possibly be a valid SYLK file, but Excel claims it thought
it was, to no avail.
Simply rename `ID' to `Ident' or `Id' or something similar.
