I was misled by a typo in the man page for file, where it says:

    Under Windows, 'file' can also be used with 'description =
    "clipboard"' in mode '"w"' and '"w"' only.

Presumably that should be "in modes '"r"' and '"w"'."

In the ?load page, I see the words "suitable connection", but I don't
see any mention of binary access being required.  Is that documented

I guess it comes from the use of gzcon in load.  Couldn't the
restriction be removed by having gzcon treat any text mode connection
as uncompressed?
