Damn.  I thought I had fixed that.

I added dolt to libX11 just before the revelation that += needed to be
replaced.  Commit b4b5893f has been pushed with the same change which
was made to the dolt script in xserver:

-        *) args+=("$arg")
+        *) args@<:@${#args[@]}@:>@="$arg" ;;

My understanding is that that should be compatible with Bourne shells in
general.

Thanks for the heads up!
