Yes, I think you're right!

That's what I meant. The name is passed on exactly as given, only the part to
the right side of the '=' gets url-encoded.

Yes it is. The reasoning behind this change is that I imagine using this
option within a shell script or similar, and then we'll use something like:

   --data-urlencode field=$moo

... and if we for example get some more or less random input in the variable
$moo, we would get some funny effects if $moo would start with the letter '@'.
Thus, I want a clear separation between the encoding of a given string and the
encoding of the contents of a given file.

We can solve the problem in other ways too, but this is what I came up with
and I couldn't figure out any other approach that is clearly better.

Yes, you can encode GET forms too with this, since you can always use -G to
convert a POST into a GET like that.
