Unless Eli can suggest how to fix `(space :align-to (- right (,hpos)))
to work on TTY frames the same way as it works on GUI frames,
I could try to rewrite it to avoid the keyword `right', i.e. to use
`(space :align-to (,hpos-from-left)) where hpos-from-left could be
calculated by using string-pixel-width on the text from the left side.
