I agree. It's a failure of the enhanced mode implementation.
The current code is reduced to counting characters and approximating
their net width so that it can place them properly.  A better
implementation would somehow tell the svg interpreter to save/restore
a particular position so that we can return to it later.=20

The corresponding terminal entry points at ENHsvg_open() are marked
=46IXME, waiting for someone who knows svg better than I do.
