Test whether tramp-encoding-command and tramp-decoding-command actually work?

[Kai.Grossjohann@CS.Uni-Dortmund.DE (K. )]

Maybe it would be a good idea to test whether tramp-encoding-command
and tramp-decoding-command actually work, before trying to use them.

But I don't know what would be a good strategy for doing this?

If the decoding command is DECODE, then it's called like this:

    DECODE > foo <<'EOF'
    ...
    EOF

Here, foo is a file on the remote host.  If the encoding command is
ENCODE, it's called like this:

    ENCODE < foo

Again, foo is a file on the remote host.

Suggestions?
