I'm just saying that it makes exactly as much sense as ctrl-E or any other control char, it has no special status.

There are quite a few ASCII control characters [1] that could make more sense than EOT, e.g., \t, \n, \e, etc.

But yes, EOT is not the only nonsensical character that you could put in a file name, and I never claimed such.
