Comment:

 Hang on.  Isn't this already handled in onion_populate_cpath() with the "!
 using_ntor" case in:
 {{{
       /* This circuit doesn't need/shouldn't be forced to have an ntor hop
 */
       if (circ->build_state->desired_path_len <= 1 || ! using_ntor)
         return 0;
 }}}

 I just tried building the maint-0.2.4 branch with --disable-curve25519 :
 everything worked okay, and it built circuits just fine.  I also verified
 to see that it works with --enable-curve25519 and "UseNTorHandshake 0".
 Then I tried the same cases on master, and that worked too.

 Did anybody check to see if this bug was actually happening?  I think we
 can close it as "worksforme", unless you think we should retroactively
 clarify the changelog.
