(e.g., "added FOO argument", "change the default start revision from 1 to 0",
etc.)

You should declare encoded_prophash here, since it isn't used outside this block.

Why is it called encoded_prophash?

Huh? Just use svn_stream_empty(), since propstring is always "" here.

Need SVN_ERR() around the close().
