Another idea would be to use "--binary" as a modifier, which would cause the
(binary) data to be uu- or base64-encoded and stored as text.
--binary would automagically convert back and forward in pe, ps, and pg.

So the proposed
        svn propedit --editor-cmd=gimp-1.3 icon myfile
would work as
        svn propedit --binary --editor-cmd=gimp-1.3 icon myfile

I live with meta-data for data in the windows registry - and it's (IMHO) just
for deciding which encoding to use for display/editing (strings as text,
binary as hexdump, dwords as numbers).

We could achieve something similar simply by storing the mime-type before the
base64-data; then any browser could decide how to display the data.

But I'd prefer to have that inline in the property-value - just to have the
thing and the type *really* together, and to avoid having (above mentioned)
